摘要: Abstract The influence of the characteristics or microstructure Portland cement on compressive strength up to 28 days has been statistically investigated by application partial least square (PLS) analysis. main groups were mineralogy and superficial represented curves from X-ray diffraction analysis differential thermogravimetric analysis, as well particle size distributions. PLS gave maximum explained variance in at 1, 2, 7 93%, 90%, 79% 67%, respectively. high makes prediction reliable. ability it possible this case predict vice versa. Such a can be utilized design achieve target performance.
