Swelling characteristics and hydraulic properties of GCLs under vertical stress were studied through hydration swelling tests and permeation tests.
通过水化膨胀试验和渗透试验研究了GCL在竖向应力作用下的膨胀特性和渗透性能,并分析了正应力和加压水化顺序的影响。
The brick has nicer characters include low hydrate expand ratio, well anti-freese quality and well resist-alkali.
通过调整配料及其化学组成,在一定温度下,采用低温素烧高温釉烧,可烧制高性能面砖,特别对降低砖的水化膨胀率,改善抗冻性和耐碱性能收到明显的效果。
