Crush Sand can vary depending on the type of manufacturing unit such as jaw crusher or VSI or any other technology. but crush sand is easy to identify as its just a crushed rock sand. You should check the all properties of crush sand such as gradation, water absorption, specific gravity etc. before doing mix design and should only be used …

Stone crusher dust can replace up to 50% sand in production of paver blocks without decrease in physical & mechanical strength [16]. In this study, NCA was replaced by coarse RCA and river sand by SCD for manufacturing of M−40 grade concrete paver blocks and mechanical & durability performance were evaluated. ... Water absorption test was ...

This will aid in lowering the water absorption rate of manufactured sand during the concrete making, resulting in improved workability and strength, and durability retention. ... so does the requirement for cement and water to connect the sand to coarse aggregates. ... Due to the higher costs of river sand, the lack of suitable crusher setup in ...

The absorption looks very high, if it is sand is it a river sand or Sahara sand. It could be lightweight (low density), as low density aggregates has relatively high absorption capacity.

Water Absorption: Water absorption is the ability of a material to absorb water. Fine aggregates have air voids in between the particles, and the water absorption property measures the amount of water that can be absorbed by these voids. It is expressed as a percentage of the weight of dry fine aggregate.

To perform the specific gravity and water absorption tests on aggregates, follow these steps: Begin by washing approximately 2 kg of the aggregate sample thoroughly to …
