Concrete Seal When conditions are encountered which in the opinion of the Department and Consultant make it impracticable to dewater the foundation before placing concrete, he may require or allow the construction of a concrete foundation seal below the elevation of the bottom of the foundation, of such dimensions as may be necessary.
Factors affecting the choice of mix proportions. The mean compressive strength required at a specific age, usually 28 days, determines the nominal watercement ratio of the mix. The other factor affecting the strength of concrete at a given age and cured at a prescribed temperature is the degree of compaction.

It was found difficulty in obtaining high strength concrete with this cement. The consumer has been normally finding it difficult to get consistent and ensured supply of high strength cement for prestressed concrete and certain items of precast concrete. For these special requirements BIS published IS:8112, Specification for OPC43 Grade cement.
Concrete mix shall be of M20 (1:1½:3) grade. Concrete pouring shall be machine mixed and mechanically vibrated. PARAPET WORK: Single brick work shall be used for the parapet work. PCC BELOW FLOORING: Plain Cement Concrete 1:4:8 using 20MM downgraded aggregates as per standard structural and architectural specification.
Average 28 days compressive strength of at least three 150 mm concrete cubes prepared with water proposed to be used shall not be less than 90% of average of strength of three similar concrete cubes prepared with distilled water.
For, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are either by volume or by mass. The .
