The flexural strength co-relation studied for manufactured sand in self compacting concrete is mentioned by Kothai and Malathy (2012). Ahmed et al. (2014) have assessed the square root (n = 1/2 ...
A self-compacting concrete and machine-made sand technology, which is applied in the field of building materials, can solve the problems of inability to guarantee high fluidity, poor concrete fluidity, and irregular particle shape, so as to improve the self-compacting performance of flow, reduce hydration shrinkage, and increase flow sexual effect
A structural concrete mix with a target compressive strength of M40 was developed using a binder composed of 65% Ordinary Portland Cement (OPC) and 35% fly ash. Manufactured sand (M-sand) was employed as a partial replacement for river sand at various levels: 20%, 40%, 60%, 80%, and . To maintain consistent workability, the amount of …

Self Consolidating Concrete (SCC) is sometimes referred to as self compacting concrete. Self conso lidating concrete is an acceptable and valid term for using superplasticisers and stabilisers in a concrete mix to significantly increase the fluidity. SCC does not require vibration. It fills the formwork by means of its own weight without any ...

Self-compacting concrete (SCC) is extensively applied in many construction projects due to its excellent fresh and hardened concrete properties. In recent years, manufactured sand (Msand) produced by crushing rock deposits is being identified as a suitable alternative source for river sand in concrete.

Self-compacting concrete (SCC) of high fluidity may lead to the high tendency of segregation, especially when manufactured sand (MS) is used. In this work, the rheological properties of SCC are optimized by adding nano-silica (NS) and limestone powder (LP) at different water-to-binder ratios (W/B).
