【摘要】:通過(guò)簡(jiǎn)單直觀的試驗(yàn)方法驗(yàn)證裂縫增加了混凝土的透水性。試驗(yàn)采用的試件為U形梁,養(yǎng)護(hù)在室溫(23℃)相對(duì)濕度為50%的環(huán)境中,通過(guò)加載使試件底部產(chǎn)生均勻裂縫,測(cè)量在不同的養(yǎng)護(hù)期,以試件質(zhì)量的損失來(lái)評(píng)估裂縫對(duì)混凝土透水性的影響。試驗(yàn)數(shù)據(jù)結(jié)果表明:當(dāng)試件的相對(duì)濕度大于周圍環(huán)境相對(duì)濕度時(shí),試件失水;差值越大,失水速度越快;當(dāng)相對(duì)濕度減小到與周圍環(huán)境相對(duì)濕度相等時(shí),試件停止失水,失水率達(dá)到峰值。裂縫增加了這個(gè)過(guò)程的速度,加大了失水的速度,增加了混凝土的透水性。
