چکیده
Abstract Self-consolidating concrete (SCC) is one of the trending low-yield stress material innovations new age building industry due to its ability flow through heavily reinforced structural members without segregation and losing moderate viscosity. In this research paper, a V-funnel simulation has been developed for time establish validity with allowable design conditions according European standard. The Bernoulli’s equation continuity state were adopted 515 mm upper width, 75 thick, vertical dimensions (depth) 450 150 V-section funnel duct (75 × 65 mm) respectively. Concrete shear wall was considered as factor unit weight (ρ) frictional force under downward velocity respect variational height (dh). result shows that kinematic viscosity (η) bound within limits 0 1/64. This implies η min ≈ (no friction walls), minimum (T ) becomes 8.7 sec while zero (τ N/m 2 ). However, max 1/64 (maximum walls τ ρ/64 attained) T 18.9 sec. These values fall after 10 seconds mixing, ranging between 8 seconds, 5 minutes mixing 11 25 Guidelines self-consolidating concrete. results placement during construction, are also consistent United Nations sustainable development goals (SDGs) technological innovation, infrastructure, cities.

Autogenous Shrinkage of Prestressed Self-Consolidating Concrete
Shrinkage can be critical factor for the design of structural members due to the length changes by the timedependent deformation. Given the high fluidity and different mixture proportions of SCC, the shrinkage of such concrete can differ from those of conventional concrete or HPC of normal consistency. Proper estimate of autogenous shrinkage of self-consolidating concrete (SCC) can provide engi...

The new generation of innovative projects has led to the use of greater amounts of reinforcement and the development of concrete with specific characteristics. It is necessary to use a material that ensures the uniformity of the cross section, as well as the adherence of the existing reinforcement, and due to this, the self-consolidating concrete becomes an technique alternative has great poten...
متن کاملStability of Self-Consolidating Concrete Containing Different Viscosity Modifiers
The main objective of this paper is to assess the effect of different viscosity-enhancing admixture (VEA) types and concentrations on deformability and stability of self-consolidating concrete (SCC). Two polysaccharide-based VEAs, one cellulose-based VEA, and a modified-startch VEA are used in this investigation. Regardless of polymer type, results showed that the incorporation of VEA leads to ...
