【摘要】 本文研究了聚合物、硅粉和改性硅粉对混凝土强度的影响,实验数据表明:掺加硅粉和改性硅粉的混凝土抗压强度和抗折强度都有所提高;掺甲基纤维素、苯丙乳液、聚醋酸乙烯乳液、乳胶的混凝土的抗折强度也达到了空白混凝土的水平。更多还原

【Abstract】 This paper studies the influence of polymer,silica fume and modified silica fume on the strength of concrete.The experimental data shows that the compressive strength and flexural strength are increased after the concrete is mixed with silica fume and modified silica fume.The flexural strength of concrete mixed with methyl cellulose,styrene-acrylic emulsion,polyvinyl acetate emulsion and latex has also reached the strength of plain concrete.更多还原
