Abstract
Based on the Compressive strength, workability and raw material consumption of concrete, a mathematical model is established for mix proportion design of high performance concrete (hereinafter referred to as HPC) with chlorine ion’s diffusion coefficient and per cubic meter cost as its optimized objectives. Matlab’s Sequential Quadratic Programming method is used for the solution of constrained nonlinear problems, with which the calculation and optimization of mix proportion of concrete are solved satisfactorily. HPC with optimized design can meet all requirements for its type and has obvious economic benefit.
