Concrete is taken for granted by most. We walk all over it. It is the most used construction material.
The cement used to bind the aggregates together has changed and understanding the importance of managing the moisture content to achieve proper curing has become more crucial. Let's discuss the components used to produce concrete.
Concrete consists of about 60% to 75% aggregates, both coarse and fine. Concrete includes 14% to 21% water, and 7% to 15% cement, there can also be as much as 8% air entrainment in a mix design.
The aggregates are produced in the field and while certain Quality control procedures exist, the reality is the aggregates are different all over the country.
This means our field produced concrete is lacking in quality control because the aggregates are mined in all different parts of the country and therefore we have a situation where different salts and heavy metals are attached to the molecules of those aggregates.
So the raw material that makes up about 70% of our product is not the same every time it is produced.
