River Sand vs Manufactured Sand
The natural river sand was the cheapest resources of sand. However the excessive mining of rive bed to meet the increasing demand for sand in construction industry has lead to the ecological imbalance in the state. Now the sand available in the riverbed is very coarse and contains very high percentage of silt and clay. …
Manufactured Sand (M-Sand) in Construction | Advantages & Disadvantages
M-sand is “crushed aggregates produced from hard granite stone which is cubically shaped with grounded edges, washed and graded with consistency to be used as a substitute of river sand”. Advantages of M sand Greater DurabilityM-Sand has balanced physical and chemical properties that can withstand any aggressive environmental and climatic conditions as it has enhanced durability, …

Why we can’t use sea sand in building construction?
We do not use use sea sand in construction due to following reasons Sea sand tends to very fine and rounded, Smooth rounded particles would offer less resistance to rearrangement than angular or elongated particles with rough surfaces. In sea water, chloride is present which will cause corrosion of steel and iron which ultimately leads …

Can desert sand be used in construction ?
Answer is both Yes and No. let’s see we should not use desert sand in construction? Desert sand grains are finer and smoother so their surface chemistry would not be able to offer sufficient number of multi-directional chemical linkages. If their grain size is too small, the slurry slip and the concrete would have poor …
Difference between initial setting time and final setting time
INITIAL SETTING TIME The time period elapsing between the time, water is added to the cement and the time, the needle fails to pierce the test block by 5.0 ± 0.5 mm measured from the bottom of the mould, is the initial setting time. The initial setting is time when chemical reaction between cement and …
