Nov 01, 2018· One of the key features of ultra-high performance fiber-reinforced concrete (UHPFRC) is the inclusion of quartz powder (QP) as a filler to optimize granular packing. However, QP has not been compared against limestone powder (LP) in terms of the filler effects, although it can affect hydration characteristics, strength development, and ...

The paper presents a concrete mix design procedure for partial replacement of sand with quartz sand. Present method was performed to evaluate the additional compressive, flexural strength with higher slump over conventional concrete in which sand is replaced with 0%, 25%, 50% and 100% of quartz sand by weight with 1% super plasticizers.
