A Practical Guide to Grouting - Parchem

Looking first at cement based grouts, these materials are essentially fine concretes - cement, aggregate and admixtures in a bag - to which we add water on site. Concrete shrinks - so does a cement based grout. What we need to do is minimise or compensate for …

The Construction and Design of Concrete Slabs on Grade

controlled low-strength material (CLSM), or lean concrete sub-base. Generally cement treated and lean concrete sub-bases are 4 to 6 inches thick. A modulus of sub-grade reaction of 400 to 500 psi/inch can be used in calculating the required thickness of floors placed directly on lean concrete and cement treated or roller compacted sub-bases.

Aggregates for Concrete

Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of

Aggregates - Portland Cement Association

Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the
