As soon as the planning for construction is finished and the forms are arranged, you should examine the type and amount of required concrete.
In order to measure the amount of concrete, just multiply the length of the slab with the width of the slab and divide by the exact number relating the depth from the chart provided under then round up to the next quarter yard.
Defining Mix Design
It is very important to determine the perfect mix for your job. Concrete specifications include Strength (PSI), Slump (mainly the thickness), Fiber Mesh, Chemical Additives as well as a Concrete Pump if needed. Generally 80% of all concrete poured remains 3000 Psi slab mix or 3000 psi pump mix. Other mixes range from 3000 Psi – 5000 Psi mixes, Fine Grout, C-476 Cell and Flowable Fill.
Compressive strength is described in psi. If it contains more psi, the strength and durability will improve. Besides, the set time will be lower with the higher PSI. Usually 80% of the slabs contain will 3000 psi.
It is suggested to use a slump of 5-6 inches (+/- 1″) as a slump superior than 6″ may delay the time and one has to wait prior to finishing, specifically in cool weather. Besides, it can enhance the possibility for shrinkage cracking.
Reinforcing Wire Mesh & Fiber MeshWhile curing of concrete, the water in the concrete starts to bleed off and the slab will begin shrinking just slightly. Shrink can lead to cracks because the slab drives across the base material. These cracks are known as shrinkage crack. With use of reinforcement like wire mesh, rebar, or fibers, the cracks can’t be avoided. It can only retain the concrete organized at the time of cracking and stop parting or vertical dislocation.
So, it is very essential to place wire or fiber mesh in the slab.
Fiber mesh is applied to substitute wire mesh in most cases, apart from the first 15’ apron of a driveway. (Verify your local codes) Reinforcing wire mesh is arranged in the slab area before pouring the wire mesh is set on mesh-ups which belong to 2” plastic chairs specifically created for wire mesh. Wire that rests on the ground and is not retained in the middle of the slab by mesh-ups, will not be fruitful for shrinkage cracks. Fiber mesh is included into the mix while pouring and is simpler to use.

Now-a-days manufactured roof trusses are used extensively for new homes in USA to form the roof. In traditional framing, the rafters and ceiling joists are used and these are replaced in prefabricated trusses. The trusses are utilized to facilitate the general contractor for building homes which contain more complicated roof and ceiling designs maintaining superior speed and precision.
Fewer unskilled carpenters are employed to build the trusses by incurring low labor costs. These cost savings will minimize the price of almost any new home to be developed. Therefore, prefabricated trusses are mostly suitable for modern builders for their bottom line as compared to traditional roof framing.
Benefits of Prefabricated Trusses
- Trusses extent longer distances and disregard the requirement for inside load bearing walls.
- Cost effective as compared to stick roof framing as they are created with shorter lengths containing two by four stock as contrary to the larger framing members associated with traditional rafter and ceiling framing.
- Trusses are specially created for almost any ceiling or roof combination essential for modern custom homes.
- The proficient engineers design these trusses to satisfy the roof load and building code requirements.
- Trusses can generally be formed in one day. Therefore, the construction time minimized significantly. The inside of the new home is uncovered outside weather conditions.
- Inexperienced carpenters will also be able to construct trusses and less labor costs are required.
The Common Roof Truss
The common truss is acknowledged by its triangular shape and will frame the bulk of any new home truss package. Common trusses include seven primary portions as below:-
Top chord - To which the roof sheathing is used.
Bottom chord - To which the drywall or other finished ceiling is associated.
Bearing point - Where the common truss is created to be placed on the outside bearing walls.
Web supports – These are used to retain the top chord in the exact position, at intermediary points from the highest to the bearing point.
King post - It is applied to facilitate support to the heighest or top of the common truss.
Metal gussets – These are applied where the web supports and king post overlap the top and bottom chord and at the bearing point.
Tail of the truss is applied to produce the eave or overhang and arranges a way to assign soffit and fascia.

(1) Raw materials utilized in Concrete Blocks :
The primary materials for developing the concrete blocks are aggregates, cement and water. Different types of aggregates are applied with changeable degree of success and they consist of crushed stones, gravel, volcanic cinders, foamed slag, furnace clinker, etc. In order to choose the aggregates, the factors like weight, texture or composition of the unit designed should be considered. The stability, texture and low-cost of the concrete block are subject to the grading of the aggregate cautiously. The cost will be reduced if locally accessible aggregate is used. The ordinary Portland cement is utilized for raw material. The required water should be the normal potable water.
(2) Concrete blocks manufacturing process:
The completely automatic plants are used to develop concrete blocks with superior strength. These automatic machines can made superior quality concrete blocks. But huge capital investment is required to set up & operate these machines. The transportation cost from the production area to the place of actual use will also be reduced for concrete blocks if the manually operated machines are installed at construction site itself.
The following manufacturing process is required for developing the concrete blocks :-
(i) Choice and ratios of ingredients: The primary factor for selecting the ingredients is the desirable strength of the block. If the coarse aggregate is mixed in perfect ratio, the strength of the quantity of cement applied will be superior.
(ii) Blending of ingredients: The aggregates, cement and water should be blended in a proper way. The mixing should be done through a mechanical mixer. While mixing manually, great care is necessary to check that the cement and aggregates are initially blended comprehensively in dry state and the water is then included slowly.
(iii) Positioning and vibration: The mixed concrete material is delivered into the mould box up to the top level and check carefully that the box is filled uniformly. The vibration of concrete is performed until it is set evenly in the mould box.
(iv) Curing: The block is drenched with water after around one day of casting and it should be sustained for at least 7 days and if possible up to 28 days. If the time for curing extends for a prolonged period, the block will be superior.
(3) Benefits of concrete blocks:The application of concrete blocks as a masonry unit is found on several construction sites due to the following benefits:
- It extends the carpet area of the building due to the small width of concrete block with regards to the brick masonry wall.
- It offers superior thermal insulation, improved fire resistance and strong absorption capacity.
- It can save major agricultural land which is applied for manufacturing bricks.
- The blocks are developed in an efficient manner so that the vertical joints can be taken back automatically and so the time spent for the careful supervision is minimized.
- The process for developing concrete block masonry is simpler, rapid and stronger as compared to the brick masonry.
- The shape and size of the concrete block is very accurate and it simplifies the work of a mason.
- As the numbers of joints are minimized, the time is saved for developing the mortar.
- The utility will be augmented by creating the reinforced concrete block (RCB) masonry units. The blocks are provided with two holes for arranging perfect reinforcing bars and the structure with RCB units could carefully withstand wind and earthquakes, if so designed. The conventional beams and columns are totally removed and the structure with RCB units will have a superior appearance.

Grillage Foundation design is mostly suitable for heavy structural loads from columns, piers or beams which are essential to transmit bearing capacity of a soil relatively inferior.
The grillage foundation can easily disperse the load over a broad area of the subsoil. This foundation facilitates to resist deep excavations because the required base area is arranged for the load of the transmission. The foundation depth is restricted from 1m to 1.5m.
The grillage foundation contains two or more tiers of beams placed at proper angles to disperse the load over a extensive area.
Usually, this type of foundation is undertaken toward heavy structure columns piers and stanchions. Grillage is made with steel I I section (R.S.J) placed in single or double large.
The second larger - The number of R.S.J.S and they’re spaced separately based on load of the structure and the bearing capability of the soil.
Ground Improvement with inclusion of Load or enhancing operative stress
When load is delivered on the ground, it is compressed. The range and required time may vary according to the placing of ground particles, on the degree of saturation as well as smooth draining of the soil. If load is delivered for loose and specifically unsaturated fills, it can cause quick settlement.
In order to build a grillage foundation, a trench of the essential width and depth is excavated. The trench surface is leveled and rammed. Above the rammed surface, a cement concrete layer is applied. It should be condensed properly to transform it water-resistant. R.S.J.S contain necessary dimension that are place at consistent gaps. For implanting the lower flanges of the R.S.J.S into the concrete, rich cement mortar is poured. The pipes and bolts are used to attach the R.S.J.S collectively. The bolts are pushed into web of the R.S.J.S.
G.I. pipe pieces are arranged among R.S.J.S, and a long bolt is passed over all the holes and pipes. This will attach the R.S.J.S collectively and develop a solid mass.
Grillage Foundation Types
1.Steel Grillage Foundation
Steel Grillage Foundation is developed with steel beams and it is structurally called rolled steel joists (RSJ), applied in two or more tiers.
2.Timber Grillage Foundation
Timber grillage is undertaken for heavy load wood column or masonry wall. Benefits of Grillage Foundations.
Steel grillage foundation is more useful for contractors as compared to wooden grillage.
Installation Speed – Contractors can make significant savings in time through a grillage foundation.
Suitability – Grillage foundations are mostly used in place of poured concrete and huge time is saved because of smooth installation process.
Costs Reduction – Contractor can obtain discount in cost as there is least possibility for disarrangement of transport infrastructure.
Multipurpose foundation solution – The technology supports various applications.
