Concrete Research Papers

Concrete specimens (cubes, cylinders and prisms) were cast and tested for compressive, split-tensile and flexural strengths at 0% (control mix), 10%, 20% and 30% replacement of sand by weight with iron filings after curing in water for 28 days. The results obtained showed that the compressive strength of concrete increased for the 10% and 20%

PDF The Use of High Performance Admixtures in Precast Concrete

precast concrete must often be designed for higher 28 day strengths than those specified, or must be manufactured in a way that increases early strengths. Changes to the concrete mix design can be used to increase early strength including the use of higher cement contents; the use of HE cement in place of GP cement; or the use of admixtures.

Foam concrete - Wikipedia

Foam concrete, also known as Lightweight Cellular Concrete (LCC), Low Density Cellular Concrete (LDCC), and other terms is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete; it may be called "foamed cement

Overview « Hycrete, Inc

In two ways: 1. Hycrete admixtures reduce water and chloride ion transport through concrete by blocking concrete pores. This blocking mechanism is a result of Hycrete's reaction with the calcium within the cement creating an oil-like molecule that repels water (not simply enhancing density as with traditional integral waterproofing alternatives). ). Less water and fewer chlorides are able to
