A comprehensive research study was carried out to determine the effect of binder type and content on the variations in lateral and pore water pressures that can be exerted by self-consolidating concrete after casting and up to early stages of hardening.
Test results show that both physical and chemical phenomena can influence the kinetics of the decrease in lateral pressure until cancellation.
This prompts contractors and engineers to design for full hydrostatic pressure, which increases construction cost made of SCC.
âVariation of Formwork Pressure with Thixotropy of Self-Consolidating Concrete.â ACI Materials Journal, Vol. âUltra-High Per- formance Fiber-Reinforced Concretes.â Groupe de travail BFUP, Paris, France. This work focussed on capturing existing knowledge and undertakening experimental program to evaluate lateral pressure developed by SCC.A portable devise for measuring lateral pressure and its rate of decay, test methods (portable vane and inclined plane tests) for field evaluation of relevant plastic and thixotropic properties of SCC that affect formwork pressure were developed.Books Info: SCC is a flowable concrete that can placed without consolidation.
Due to lack of knowledge on SCC lateral pressure on formwork system, its use in cast-in-place applications have slowed down.Such pressure is expressed as: P[subscript max] = p × g × H where p, g, and H correspond to the concrete unit weight, gravity, and head of concrete, respectively.Such approach can result in increased construction costs and can limit the rate of rise of the concrete in the formwork.Regrettably, presently we can't give you information about the Writer Omran Ahmed Fathy.However doesn't imply that individuals do not work on the series.The study investigated the role of material constituents, casting characteristics, and formwork geometry on SCC form pressure.
