Mechanical Properties of Ultra-High Performance Concrete ...
utilize WFS in high-strength, normal and low-strength concrete and WFS can positively impact their mechanical properties [2–4,8–16]. The new generation concrete, ultra-high performance concrete (UHPC), has high compressive strength exceeding 120 N/mm2 [17–19], or according to other references 150 N/mm2 [20–22].
Re-usage of waste foundry sand in high-strength …
The high replacement of the blended foundry sand caused a reduction in strength as compared with concrete incorporating white sand or waste foundry sand. Naik et al. (2004) studied the influence of waste foundry sand as well as fly ash and bottom ash on the compressive strength of bricks, blocks, and paving stones.
