Proportioning of Plain Cement Concrete. Proportioning is crucial and can vary based on specific requirements or specifications. Typically, a 1:2:4 or 1:3:6 mix is used. Measurement can be achieved through weight batching or volume batching, with the latter involving the use of a suitable measuring box equivalent to one bag of cement.
CEMENT: Three types of cement are in general demand for concrete products. They are types I, II, and III of Federal and A.S.T.M. Specifications. Type I, or ordinary cement, is used where extended curing periods are no handicap, or where blocks can be yarded for 7 to 28 days, allowing time for the blocks to attain specification strength.
