Understanding Polymers in Concrete| Concrete Construction ...

Sep 15, 2001· There are many reasons to add polymers to concrete overlay mixes. Polymers improve adhesion to the old surface, flexural strength, tensile strength, and freeze/thaw durability. They also reduce permeability, the intrusion of chlorides, salts, and carbon dioxide. They increase abrasion resistance and can be applied in very thin cross sections.

Concrete Admixtures – Types and Functions – Cement Concrete

A 0.5% concentration of admixture by weight of cement can increase slump from 25mm to 100 mm. (iii) BY the addition of the admixture, concrete with the same workability and compressive strength can be obtained at lower cement content. A 0.5% concentration of admixture by weight of cement may require 15% less cement.

How to Rapidly Speed up Concrete Drying Time

How Long Does Concrete Take to Dry? According to the Portland Cement Association, once conditions are conducive for the concrete to dry — that is, consistent, reasonable heat in the air and low relative humidity — it typically takes about 30 days for every one inch of slab thickness to dry to 85-90% relative humidity. We say 'once conditions are conducive' because concrete that was put ...
