Static Modulus of Elasticity Of Sand-Laterite Blocks
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 1
Abstract
There is little documentation with regards to some structural characteristics of masonry units. Inadequate information on these characteristics leaves room for much speculation, approximations and arbitrariness, which could be detrimental to the design of structures. Static modulus of elasticity of sand-laterite blocks was determined in this work. Simplex optimization technique was used to formulate mathematical model for optimization of static modulus of elasticity of the blocks. Statistical tools were used to verify the adequacy of the model. The model proved satisfactory. With the model, values of static modulus of elasticity can be obtained if the mix ratios are specified. It can also provide the mix proportions that will give a desired value of static modulus of elasticity. The maximum value of static modulus of elasticity of sand-laterite blocks obtainable from this model is 6.414GPa.
