DynaCreteŽ PIM+ maintains correct moisture levels throughout curing process, keeps the integrity and consistency of the cement gel, and permanently seals the concrete, resulting in a Higher Quality concrete. |
Fact:Cement gel is a jelly-like swelling that occurs around each grain of Portland cement when water is added to the concrete mix. Aggregate gel is essentially the same. It is the initial reaction between cement and water. The gel is the controlling factor in cracking, uniformity, and structural quality of concrete. Cement gel relates to the size of the voids and pores in the concrete. The cement gel imparts fatty and cohesive properties to the mix. As hydration of the cement proceeds, the gel partly crystallizes and, on drying, reverts to almost the original cement grain size. Gel size and hydration vary widely, depending upon water and temperature. It is this difference that causes variations in the quality of concrete for a given mix design. In the heat of summer, gels form faster and longer. Large gels absorb more water from the mix, thus, resulting in poorer quality concrete. As water is consumed by hydration and rapidly lost through evaporation, internal stresses are created. The eventual results are shrinkage cracks. In cooler weather, gel formation is retarded. Smaller gels are formed, and less mixing of water is needed. Concrete quality is proportionately better. Water hydration is slower, less shrinkage occurs, concrete is denser, and usually has a higher structural quality. Therefore, the gel is the governing factor in controlling uniformity, structural quality and cracking of the concrete. Recommendation:Due to its chemical reaction, DynaCreteŽ PIM+ forms a silica aero gel, which maintain optimum moisture levels in the concrete throughout the curing process. This helps in keeping the integrity and consistency of the cement gels constant throughout the concrete. After the curing process the concrete is densified, hardened and permanently sealed This results in a higher quality of the concrete. Our certified applicators will get you the results with 100% warranty on their workmanship. Concrete is not only aided in curing, but also sealed in one application, therefore less down time for other trades people and no time limitations; ie. most sealers can't be applied for 28 days after the concrete is poured.
