How to Reuse Old Concrete Slabs eHow

How to Reuse Old Concrete Slabs eHow

Leftover concrete is a valuable source of material, often used as a subbase layer for other projects. Because recycling concrete can cost as much as 100 a ton, reusing old slabs is not only a greener alternative, it can help you source building material at a lower price. Putting old building material to work only takes a few steps.

Mechanical Performance of Concrete Made with Recycled

Mechanical Performance of Concrete Made with Recycled

Sep 15, 2020 Therefore, recycled concrete has the same optimum sand ratio as conventional concrete. Using this sand ratio, recycled concrete can obtain maximum compressive strength and flexural tensile strength. Through a large number of experiments, when the replacement rate of recycled aggregate is 30, the optimal sand ratio of recycled concrete is 38 ...

What are the Correct Concrete Mixing Ratios Ratio Chart

What are the Correct Concrete Mixing Ratios Ratio Chart

When making your own concrete its important to use the correct concrete mixing ratios to produce a strong, durable concrete mix. Some basic mixing ratios for concrete are 123, 133, 124. These mixing ratios are based on the proportions of cement sand stone in that order. The ratio you use will depend on what psi strength you need.

Can I Make Concrete with Just Sand and Cement

Can I Make Concrete with Just Sand and Cement

Aug 13, 2020 You cannot make concrete with only sand and cement because it requires a coarse aggregate like gravel. The stone component is the most critical, as that is what gives it its durability and strength. When mixing merely sand, cement, and water, you get a material closer to mortar. You can purchase concrete with a high sand content or even a no-fines concrete where they exclude entirely sand
