Void Ratio – If you fill the shuttering area with blue metal alone it has lots of voids in it which also need to be filled by the other materials such as sand & cement. Such void gap is known as void ratio compressibility which is 20% for coarse aggregate. So if we need 1 m3 of concrete in wet condition we have to take consideration of the

Get PriceCement stabilized earth blocks are used an alternative building material for burnt clay bricks and cement, sand blocks. This is an appropriate and cost-effective wall construction material as most of the generally available sandy soil and gravel soil can be used for manufacturing of these blocks. Soil can easily be extracted and easily processed for production of these blocks. Soil is mixed in
Get PriceDo not use cement that has hardened or become lumpy as breaking it up will only produce concrete of poor strength. Sand — Ensure the sand or fine aggregate is clean and does not contain clay, organic material or salt. Generally, 'brickies' or 'plasterer's' sand is not suitable for concrete due to its high clay content but can be used to make mortar. Coarse aggregate — River
