Uses and benefits of dry pack mortar in job site

Dry pack mortar also known as deck mud or floor mud, is formed by blending sand, cement, and water. It’s application is found in repairing small spots, developing thick bed mortar for tile and brick placement, and bed shower setting up.

The proportion of the mixture is done with one part of cement to four part of sand, and sufficient water is required to form mortar that bind together while it is molded into a ball manually.

After being added, the ball shall not decay due to low water quantity and should not slump because of to high-water proportion. This mixture is supposed to produce a compressive strength of 21 MPa.

Dry Pack Mortar – usages and benefits

Mixture Proportion: It is found that one part of cement to four part of sand, desirably sharp clean sand, is sufficient. Further, mix proportions like one to two and half, and one to five or even six are recommended.

Mixture Proportion: It is found that one part of cement to four part of sand, desirably sharp clean sand, is sufficient. Further, mix proportions like one to two and half, and one to five or even six are recommended.

In terms of quantity of water, it is based on the moisture content of the sand being utilized. When moisture of sand is low, larger quantity of water is required in respect to where moisture content is high.

1. Developing ordinary thick mortar beds.
2. Leveling of concrete surfaces up to 51 mm thick.
3. Suitable for floating shower bases.
4. It is directly connected or applied as a isolated floating mortar bed over a cleavage membrane or waterproofing membrane.
5. Suitable for both residential and commercial applications in dry and wet areas.
6. The purpose of dry pack mortar is to fill deep holes in a concrete wall. When the dry pack mortar components are blended, it should be arranged in layers of 10mm and then compressed with hammer, stick, or hardwood dowel. Instead of wooden stick, the metal stick should be utilized to compress dry pack mortar since metal stick produces greater compaction and as well as bond. Besides, it is direct tamping should be employed at an angle to the sides of the hole to maintain good compaction at the sides of the hole.

Benefits of Dry Pack Mortar

1. Applicable for Interior and Exterior applications
2. Mixing of sand and cement in construction site is not necessary
3. It is easily tamped, compacted, and sloped
4. It ensures a consistent mix on large jobs

Use and benefits of self compacting concrete

Self-consolidating concrete alias self-compacting concrete (SCC) is a concrete mixture that can flow into very complex forms with various reinforcing bars (rebar congestion) and leaves no voids.

It can be arranged with its own weight devoid of any mechanical vibration. SCC retains all the conventional mechanical and durability characteristics of concrete.

With extremely fluid nature of SCC, it becomes possible to arrange it in complicated conditions and in sections with congested reinforcement. It can also reduce hearing-related damages on the worksite due to vibration of concrete. In SSC, the required time is curtailed significantly for arranging bigger sections.

In some cases, the superplasticizers and viscosity modifier are provided to the mix to minimize bleeding and segregation.

A well designed SCC mix never segregates because it contains extreme deformability and outstanding stability characteristics.

Self-Compacting Concrete Properties: Self-compacting concrete has good resistance capacity against segregation as it applies mineral fillers or fines as well as special admixtures. Self-consolidating concrete is essential to flow and fill special forms under its own weight. It is flown adequately to travel over extremely reinforced areas, and should have capability to circumvent segregation of aggregate.

Self-compacting concrete contains an equivalent water cement or cement binder ratio that provides normally a slightly higher strength with regards to conventional vibrated concrete and because of non-existence of vibration, a better interface among the aggregate and hardened paste is created.

The concrete mix of SCC should be arranged at a comparatively greater velocity as compared to regular concrete. Self-compacting concrete is placed from heights longer than 5 meters exclusive of aggregate segregation. It is also useful for areas having normal and congested reinforcement, with aggregates as large as 2 inches.

Self-Compacting Concrete Uses - Self-compacting concrete is mostly utilized in bridges and even on pre-cast sections. This type of concrete is suitable for the following:

• Drilled shafts
• Columns
• Earth retaining systems
• Areas with high concentration of rebar and pipes/conduits
