Manual mixing is not recommended until and unless trained skilled worker carries out the work in a systematic manner. Machine mixing is faster and more efficient than manual mixing. It is often observed that mixers used in our country are not properly designed to cater adequate mixing of concrete materials.
Sand is the most available construction material in Bangladesh. Sand cement stabilization is more cost effective and environment friendly for the construction of subbase pavement layer in perspective of Bangladesh. The researchers conducted an investigation for the use of cement stabilized fine to medium sand in the construction of roads.
The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud.
Consequently it is used in only a few applications such as a dampproof course or in some limited areas where heavy loads are expected. A 1:3 mix using fine sand is usually required to get adequate plasticity. Compo mortar is made with cement, lime and sand. In some localities a 50:50 cementlime mix is sold as mortar cement.
This process will make sure that there are no large rocks within the material. It is most commonly used to as a key ingredient in cement or hot asphalt but can also be used as pipe sand or as a base layer and leveling medium for above ground pools, and patios or walkways made of concrete paving stones. Mason Sand. Mason sand is created in the ...
