Barite powder as sand substitution in concrete: Effect

2015-10-1  In S5 mixture, 5% of the sand volume was substituted by barite. There are various methods to design concrete formulation. The basic principle of most of them is based on the search of the maximum grain compacity [26]. Some methods use a “reference curve” supposed giving the maximum compacity with the used materials.

Barite powder as sand substitution in concrete: Effect

The effect of sand substitution by barite powder on concrete has been examined. Limestone skeleton should be conserved to reduce the compressive strength loss. The use of barite induces a reduction of elasticity modulus around 20%. Replacing sand by barite reduces the tensile strength of concrete to half.

Simulation of ultra-high-performance concrete mixed

2020-12-10  In this study, high-density materials, as a replacement to sand, were mixed with UHPC. Silica sand was also compared with barite and hematite. This present study mainly aimed to investigate the suitability of some natural high-density minerals (e.g., barite and hematite) in producing “high-performance heavy density concrete” that could provide better absorption against γ -rays than silica sand.

Compressive Strength of Concrete Using Sawdust as

2016-9-9  density of sand is higher than the density of sawdust, therefore as sand is replaced by an equal volume of sawdust the mass of the mixture reduced, leading to a decrease in density. An equation of ρ=0.0239x2-0.6.4806x+2330.9 with an R2value of 0.9866 may be used to represent the variation of the 28-day density of concrete (ρ) with sawdust replacement
