To reduce the cement based content, both the water content and cement content must be reduced as much as possible. Concrete mixes with fewer micro cracks can be produced by blending the cement with mineral admixtures either in the batching plant or in the cement plant. This enhances the service life of concrete structures in a cost-effective

States for concrete manufactured and deliv-ered to a purchaser in a freshly mixed and unhardened state. Two other specifications occasionally used are ASTM C 685 "Specifi-cation for Concrete Made by Volumetric Batching and Continuous Mixing" and AASHTO M-157, with the same title as C 94. Naturally, C 685 applies to concrete
Aug 05, 2015 · In order to determine the quality of concrete on site, it shall undergo quality tests. Here are 6 common quality tests on concrete before and after completion of casting on site. 1. Slump test before leaving the batching plant and on arrival on site. This is to determine the workability of concrete …

GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight.

Screed is quite simply a thin, top layer of material laid over a concrete subfloor, that is traditionally made of sharp sand and cement, similarly to concrete. Industrial screed can be used for more heavy duty applications by using a more coarse 6-10mm aggregate. It is used to cover structural flooring concrete, and can be applied to either a solid, in-situ or precast concrete floor slab.
