A Mathematical Model For Prediction Of The Strength Of Sandcrete Cement Block

A MATHEMATICAL MODEL FOR PREDICTION OF THE STRENGTH OF SANCRETE CEMENT BLOCK [APPLICATION OF HENRY SCHEFFE’S AND OSADEBE’S CONCRETE OPTIMISATION THEORY] Abstract Sandcrete blocks are prismatic units manufactured from lean (sand-cement) mortar mixes and are the predominant walling materials used in buildings in Nigeria and other countries. Although the blocks are preferred to other similar walling material such as bricks and concrete blocks due to the availability of the dominant material (sand) in the country and the ease of manufacture, the material is kn…
