火山岩火山灰活性及其反应动力学的研究
Study on Pozzolanic Activity and Kinetic Hydration of Volcanic Rocks
【摘要】 通过盐酸选择性溶解法测定了火山岩-Ca(OH)2-H2O系统中火山岩的反应程度,以此来评估不同种类火山岩样品的火山灰活性,并根据化学动力学理论建立了火山岩的火山灰反应动力学模型。结果表明:火山岩的火山灰反应符合一级反应动力学模型;不同品种火山岩火山灰活性的差异对水泥砂浆强度的影响不大。
【Abstract】 Reaction degree of volcanic rocks in volcanic rocks-Ca( OH)2-H2 O system was measured by acid dissolution method,which was used for evaluation of pozzolanic reactivity of volcanic rocks,and the kinetics model of pozzolanic reaction of volcanic rocks was investigated on this basis. The results show that the pozzolanic reactivity of volcanic rocks conforms with the class Ⅰ kinetics model. The differences in pozzolanic reactivity of volcanic rocks have little effect on the strength of the cement mortar.
