Applications and advantages of Slag Cement in concrete construction

Slag cement stands for a hydraulic cement that is developed when granulated blast furnace slag (GGBFS) is crushed by maintaining proper delicacy and utilized to substitute a part of portland cement. It is applied as an independently batched cementitious materials.

It belongs to a restored industrial by-product concerning an iron blast furnace. It mainly contains calcium and aluminum silicates.

Molten slag deflected from the iron blast furnace is chilled instantly. It forms glassy granules that offer required reactive cementitious characteristics when crush into cement fineness.

As soon as the slag is chilled and crushed to an utilizable fineness it is preserved and transported to suppliers. Slag cement is extensively used in ready-mixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products.

The slag cement can improve the functioning of concrete for a long period as well as facilitates the designers to minimize the environmental footprint of concrete whereas assuring superior performance and better stability.

Given below, the various advantages of slag cement application:

1. Superior functionality
2. Simpler placeability and finishability
3. Greater long-standing compressive and flexural strengths
4. Lowered permeability
5. ASR mitigation properties
6. Superior stability and resilience
7. More uniform performance
8. Lighter color

Specifications and Grade:

Grade 80: Slag containing a low activity index

Grade 100: Slag with a moderate activity index

Grade 120: Slag with a high activity index

Application & dosage (% by weight) of slag

Outside flatwork ≤35%
General application 35 to 50%
Mass concrete 60 to 80%

Sulfate resistance
Type II equivalent ≥ 35%
Type V equivalent ≥ 50%
Marine/chemical/heat >50%<80%

The slag cement is used in diverse ways which range from ternary mixtures and soil stabilization etc.

How to check the quality of cement at the construction site

The quality of cement should be examined properly prior to utilize it in concrete, plastering or any other purpose at construction work site.

For quality checking, initial inspection is very crucial. It may not always feasible to check all the engineering qualities required for utilizing cement on site but the quality of cement can be checked roughly through some recognized field test in the construction site. But the other crucial tests should be performed in laboratories.

Field Tests to verify the quality of Cement

1. Date of Packing Cement: Before purchasing cement, make proper investigation regarding the date of manufacture provided on the cement bags. It is very crucial since the strength of cement is decreased with age.

2. Colour: The color of cement should be consistent. Usually, the colour of cement remains grey with a light greenish shade. The colour of cement symbolizes surplus lime or clay and the degree of burning.

3. Rubbing: Take a pinch of cement among fingers and rub it, It should appear smooth at the time of rubbing. If it feels rough, there is adulteration with sand.

4. Temperature Test of Cement: Push your hand into the cement bag and it should feel cool. It means that there is no hydration reaction in the bag.

5. Float Test: Provide a small quantity of cement in a bucket of water. It should submerge and should not float on the surface.

6. Smell Test: Select a bit of cement and smell it. If there is excessive pounded clay and silt as an adulterant in the cement, the paste will provide an earthy smell.

7. Existence of Lumps: Open the bag and check that no lumps exist in the bag. It will make sure that no setting has occured.

8. Shape Test: Select 100g of cement and make a stiff paste. Make a cake with sharp edges and placed on the glass plate. Submerge this plate in water. Verify that the shape should remain as it is at the time of settling. It should have the capability for being set and obtained strength. Cement has the capacity of being set under water also and for this reason it is known as ‘Hydraulic Cement’.

9. Strength of Cement Test: A block of cement 25 mm*25 mm and 200 mm long is arranged and absorbed for 7 days in water. It is then set on supports 15000 mm apart and it is loaded with a weight of 340 N. The block should not demonstrate any sign of failure.

Some useful tips to draw a floor plan effectively

A floor plan stands for a scaled diagram of a room or building glanced from above. The floor plan may demonstrate a whole building, one floor of a building, or a single room. It may also comprise of measurements, furniture, appliances, or everything required for developing the plan.

The objective of the floor plans is to design furniture layout, wiring systems, and much more. They're also very suitable for real estate agents and leasing companies in allowing sell or rent out a space.

The benefits of Floor Plan Design

Floor plans play an important role while designing and building a home. A good floor plan can make a pleasant flow among spaces and can even enhance its resale value.

Given below, some useful features of a good floor plan

• Adaptable and flexible. Ensure that in near future an office can be transformed into a child's bedroom smoothly whether for your family or a future buyer's.

• Ideal room layout. Ensure bedrooms are distant from entertaining spaces. The face of the bathrooms shouldn't be directed to entertainment spaces like dining rooms or living rooms. Most people will prefer that the kitchen should be opened to the dining or living rooms in order that whoever is cooking can still keep in touch with guests or monitor on the kids playing.

• Size matters. While making design of any room or hallway, consider how many people will stay in that space all at once. Is there room for them to move around? Is there room for furniture to coordinate all the planned activities?

• Fits your priorities and lifestyle. If entertaining is crucial, ensure there's a good flow from the kitchen to an exterior space and living room.

While performing laundry work, is it perfect to climb three floors to shift from your master bedroom to the laundry room?

• Get the balance among architectural details and practical considerations. Concentrate on the security of kids, cleaning, heating and cooling bill prior to select some majestic staircase or floor to ceiling windows.

How to Draw a Floor Plan - Given below, some useful tips to draw a floor plan:

• Select an area. Find out the area that will be drawn. If the building is already there, choose how much (a room, a floor, or the complete building) should be drawn. If the building does not yet subsist, plot out the designs on the basis of the size and shape of the location where the building should be constructed.

• Get measurements. If the building subsists, work out the walls, doors, and relevant furniture to make the floor plan perfect. If the layout is to be developed for a completely new area, ensure that the total area will accommodate where it should be constructed. It is suggested to study buildings which are constructed in identical areas to be employed as an estimate for this floor plan.

• Draw walls. Insert walls for each room of the building, keep in mind that the walls should be drawn to scale.

• Add architectural features. Start adding features to the space by providing the inflexible things, like the doors and windows, along with the refrigerator, dishwasher, dryer, and other vital instruments that should be arranged in a particular location.

• Add furniture. Include furniture if it is required for the floor plan.
