Bond Performance of Lightweight Self-Consolidating

Self-consolidating concrete (SCC) is a relatively new innovation in the concrete industry that allows for the placement of concrete without consolidation. The use of lightweight (LW) concrete reduces dead loads and lowers transportation costs. LWSCC is a recent combination of the two types of concrete.

Self-Consolidating Lightweight Concrete Incorporating ...

Sep 19, 2019  However, the lightweight concrete mix design is di erent from conventional concrete. Using the conventional mix design will give rise to material segregation, as well as lower the strength by reducing the weight of aggregate. To avoid this problem, the mix design of self-consolidating concrete (SCC) was used for lightweight concrete [14].

self-consolidating concrete Topic

May 01, 2021  Self-consolidating concrete (SCC) is highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. In general, SCC is concrete made with conventional concrete materials and, in some cases, with a viscosity-modifying admixture (VMA). SCC has also been described as self-compacting concrete

consolidation of concrete Topic

May 01, 2021  Consolidation is the process of inducing a closer arrangement of the solid particles in freshly mixed concrete or mortar during placement by the reduction of voids, usually by vibration, centrifugation, rodding, tamping, or some combinations of these actions. Consolidation is needed because a mass of freshly placed concrete is usually honeycombed with entrapped air voids that are
