灰泥底料

歐億星生態(tài)壁材 灰泥如何施工 歐億星灰泥的施工方法和硅藻泥的施工方法差不多， 不同廠家灰泥的施工方法不同， 歐億星 灰泥施工注意事項(xiàng)： 材料配比及攪拌 1.按規(guī)定比例準(zhǔn)備清水，在干凈的攪拌桶內(nèi)倒入比例用水量的九成（留少量做調(diào)整用） ，然 后慢慢倒入粉體靜置浸泡 5 分鐘； 1. 用電動攪拌機(jī)進(jìn)行攪拌，開始感覺太硬，攪拌費(fèi)力是正?，F(xiàn)象，可以用 剩余少量清水調(diào)整。 3.攪拌越是均勻，材料的施工性越好，直到使物料混合均勻，攪拌時間不少于 15分鐘； 4.攪拌均勻后應(yīng)立即使用。 5.具體加水量：不同的材料加水量會有差異，另外和溫度，濕度都有關(guān)系。 試著先加標(biāo)準(zhǔn)用水量的一半就開始攪拌，然后根據(jù)料的和易程度進(jìn)行調(diào)整。 注意事項(xiàng)： 1. 當(dāng)天攪拌的漿料當(dāng)天用完； 2. 加錯水量容易發(fā)生變色，產(chǎn)生色差和裂縫。 3. 使用過程中發(fā)現(xiàn)材料變干時不得加水，用攪拌器攪拌即可。 第三道工序 下涂層施工：先用毛刷滾子

Serious failure on the slope of rock ground can be caused by a cyclic action of freezing and thawing in the cold regions. The frost susceptibilityand the effect of freezing and thawing on the rock material, however, have notbeen well investigated. In order to find out the freezing effect on the rock materials, mortar specimens are frozen as a pseudo-rock material under the constant rate of freezing by means of controlling the temperature of both endsof specimen. The freezing process is given one-dimensionally to the cylindrical samples in the laboratory to simulate the in-situ freezing phenomena in the natural ground. Formation of ice lens, frost heave and water intake during freezing process are observed on the mortar specimen under constant freezing rate, which probably causes cracks or large deformation in the real rock ground. The valuesof the velocity of elastic wave propagation are compared before and after freezing process to estimate the degree of weathering due to freezing and thawing.
