Self-Compacting Concrete—Literature Overview

self-compacting concrete can be used as a motivation to thoroughly study the influence of partially replacing natural aggregate with waste tire rubber, not only to provide lightweight self-compacting concrete (SCC) and to preserve natural resources, but also to maintain or even improve the mechanical properties and durability of SCC 2.

Concrete Slurry Recycling

Slurry Recycling is a solution for your day to recycling slurry caused by cutting, drilling, or grinding concrete Slurry waste is prohibited from being dumped in drains or traditional garbage, due to it being able to block and corroded pip because of its harmful nature slurry is the by product of concrete solids after materials have been grinned, cut or cored.

Recycled Concrete Road Base Compaction

Dec 05, 2006· But the compaction keeps coming up in the low 90's with a modified proctor, moisture looks good The contractors seem to be laying it in there and compacting it with a vibratory roller, I'm thinking they may need a larger one I'm just curios if there is some reason with recycled concrete that it wouldn't meet compaction.

Batching, Mixing, Placing and Compaction of Concrete

A secondary effect is that of grinding of the aggregate, particularly if soft; the grading thus becomes finer and the workability lower In case of air entrained concrete, prolong mixing reduces the air content Ready mixed concrete: If instead of being batched and mixed on site, concrete is delivered for placing from a central plant.
