Impact resistance and strength performance of concrete mixtures with 0.36 and 0.46 water-cement ratios made with polypropylene and silica fume are examined. Polypropylene fiber with 12-mm length and four volume fractions of 0%, 0.2%, 0.3% and 0.5% are used. In pre-determined mixtures, silica fume is
The preparation of carbon fiber-reinforced cement-based composites involved two-step dispersions of carbon fibers. Both steps affected greatly the mechanical properties of the composites. With the aid of ultrasonic wave, a new dispersant hydroxyethyl cellulose was used to help fiber dispersion in th
The correlation between compositions using particles of different two sizes and mechanical properties was studied experimentally. Spherical silica particles of 0.24 and 1.56 lm in diameter were compounded into a bisphenol A-type epoxy matrix at composition ratios ranging from 0 to 1.0 with a constan
