Mechanical Properties of Polymer Concrete

Aug 19, 2013  Polymer concrete was introduced in the late 1950s and became well known in the 1970s for its use in repair, thin overlays and floors, and precast components. Because of its properties like high compressive strength, fast curing, high specific strength, and resistance to chemical attacks polymer concrete has found application in very specialized domains.

Concrete vs Floor Screeds: What is The Difference? All ...

May 04, 2018  Concrete has a much coarser mixture than screed, consisting of larger, hard-core aggregates, which are the key element that gives it its durability and makes it strong and long lasting. Because concrete has the potential to hit very high strengths, it is used across the construction industry for structural purposes – including floor slabs.

Nov 15, 2017  In this paper, Structural Lightweight Concrete (SLC) containing Recycled Lightweight Aggregate (RLA) is described. Damaged lightweight concrete was used as RLA by crushing it into fine particles, and used to replace fine limestone aggregate of up to 45% by weight. To enhance the strength development of SLC, silica fume and a superplasticizer were incorporated into the mixture.
