Understand the role of aggregate in concrete,it should be strong enough (at least stronger than the concrete you want) – weakest phase material
for the fine aggregate component of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of securable river sand deposits and a concomitant price increase in the material. Therefore, it is desirable to obtain cheap, environmentally friendly substitutes for river sand that is preferably sea sand. The Land Reclamation and Development Board (Sri Lanka ...

crushing and the sample cube is tested to determine the compressive strength of concrete. Tests to determine the physical properties of sample cube such as specific gravity, fineness modulus, and m best alternative for the fine aggregate because fine aggregate (natural sand) and stone dust has similar physical and mechanical properties. This paper shows some relevant studies .
as aggregate in concrete ... percentage replacement of sand by saw dust the compressive strength of concrete increased with age. As the curing time increases, the reaction between cement and water continues thereby forming more CSH gel which improves the bond between the cement paste and the aggregates, thereby increasing the compressive strength. It is also seen that the compressive ...
Key words: Durability, Quarry dust, Material test. 1. Study of Concrete Involving Use of Quarry dust as Partial. as partial replacement of fine aggregates in concrete. Fine aggregates were replaced by quarry dust as 0%, 10%, 20%, 30% and 40% by weight for M25 mix. The concrete specimens were tested for compressive strength, strength ...
· The test specimens were made from three different grades of concrete, mix ratios 1: : 3, 1: 2: 4, 1: : 5, and both compressive as well as tensile strength tests were conducted. The basic strength properties of concrete were investigated by replacing natural sand by stone dust at replacement levels of 0%, 10%, 20%, 30%, 40%, 50% 60%. For the different grades of concrete .

Therefore, it is desirable to obtain cheap, environmentally friendly substitutes for river sand that is preferably sea sand. The Land Reclamation and Development Board (Sri Lanka ...
in concrete containing quarry dust as fine aggregate in resisting corrosion. 2. MATERIALS Ordinary Portland Cement (43 Grade) was used throughout the investigation. Locally available wellgraded quarry dust, conforming to ZoneII having specific gravity and fineness modulus was used as fine aggregate.
This paper explores about utilizing quarry stone dust as a fine aggregate. Abhishek Kumar and Vikram Singh, (2019) Study the Effect of Stone Dust Steel Fibre on Strength Properties of study The replacements are done at 0%, (30%, 1%), (40%, 1%), (50%, 1%) of fine aggregate with Stone dust and addition of Steel fiber 1% by the weight of cement. Design mix is prepared on M30 grade ...
