Abstract: Pumping of concrete is an efficient placement technique. When the concrete is pumped in a pipe, the lubrication layer (LL) forms and its rheological properties predominantly dictate the flow and govern the resumption ...

Abstract: Aggregate particle size distributions, shape characteristics, proportions and compaction level collectively influence packing density and, in turn, concrete properties. However, the available packing density prediction ...

Abstract: Scabbing on the rear face of concrete under impact produces fragments that act as additional projectiles causing fatality or severe damage to the occupants or systems. Ultrahigh-performance concrete (UHPC) has outstanding ...

Abstract: Pumping is a high shear process used in the placement of concrete. The lubrication layer (LL), a thin layer of micromortar, forms at the inner periphery of the pipe during the pumping of concrete, facilitating its movement ...

Abstract: The lubrication layer of concrete plays a vital role in the pumping of concrete. In the present study, the influence of different types of binders ordinary portland cement (OPC), Portland pozzolana cement (PPC), portland ...

Abstract: Studies on the characterization and performance of residual sugarcane bagasse ash (SCBA) obtained from high-temperature cogeneration boilers in concrete are highly limited. This study investigated the pretreatment process ...

Abstract: A thin layer of micromortar called a lubrication layer (LL) forms around the inner periphery of the pipe during the pumping of fresh concrete. This LL aids in the movement of concrete under pressure. The composition of the ...

Abstract: Ultrahigh-performance concrete (UHPC) has great potential for applications in civil and military structures due to its outstanding performance and ability to withstand impact and blast load. This performance can be attributed ...
