保温砂浆中的砂子起到什么作用

时间:2016-07-18     作者:www.xzalk.com【原创】   阅读

首先:砂子是什么:砂子,多为人工制造,或是从人工从某些石块上打磨下来的,颗粒相对更大一些,饱满感更强一些,拿在手中能清晰地感觉到有颗粒存在。

First: what is the sand, sand, much as an artificial, or from artificial down from some stones polished, particle relative bigger, full feeling more, hold it in hand can clearly feel the presence of particles.


其次:砂子有什么样的应用:1。在混凝土中,能同水泥分子相结合,增加水泥分子的扩散面积,形成水泥浆后,增强水泥的水化作用。2。具有一定的润滑作用,改善混凝土拌合物的和易性。3。在各类砂浆中起到骨料作用,并可有效地节省胶结材料。4。填充石子颗粒间的空隙,与石子一起共同起到骨架作用,提高混凝土的密实性和强度。5。在水泥水化过程中,有效地降低水泥水化热,抑制水泥因物理、化学反应体积变化时裂缝的产生。6。可在膨胀土、冰冻土等不良土层中充当垫层,起到了保护作用。

Second: sand what applications: 1. In the concrete, combined with cement molecules, increase cement molecular diffusion area, the formation of cement slurry, reinforced cement hydration. 2. Have certain lubrication, improve the workability of concrete mixture. 3. In all kinds of mortar aggregate effect, and can effectively save the cementitious materials. 4. Filling the space between the gravel particles, and gravel skeleton effect together, increase the density and strength of concrete. 5. In the process of cement hydration, effectively reduce the cement hydration heat, inhibition of cement for the cracking of the physical and chemical reaction volume changes. 6. Can be in the expansive soil, frozen soil, soil ACTS as a cushion, played a protective role.


砂子型的保温砂浆

The sand type thermal insulation mortar


在功能特征上继承了砂子的一切功能特点,这类类型的保温砂浆能更好的为建筑工程做出贡献。砂子型的保温砂浆应用:我国地域广阔,南北温差较大,由于保温砂浆独有的特点,在不同地区有不同的作用。夏冷冬冷地区,对建筑外墙保温要求较高,普通的保温砂浆很难满足要求。由于有机保温材料的保温效果较好,因此,在这些地方一般采用此种材料进行外墙保温。但是由于外墙墙体材料和混凝土梁柱的导热系数不同,易产生冷热桥现象,此时在梁柱外侧涂抹上保温砂浆可以减少冷热桥的产生。夏热冬冷地区是一个过渡地区,其外墙保温要求较夏冷冬冷地区要低一些。

On the functional characteristics inherited all functional features of the sand, such type of insulating mortar can better contribute to the construction project. Sand type thermal insulation mortar application: China's vast area, the temperature difference is bigger, because of the unique characteristics of insulation mortar, in different regions have different functions. Cold winters regions, the demand is higher, the heat preservation ordinary insulation mortar is very difficult to meet the requirements. Due to the organic heat preservation material heat preservation effect is good, therefore, in these places usually use this kind of materials for exterior wall insulation. But as exterior wall materials and concrete beams of different coefficient of thermal conductivity, easy to produce hot and cold bridge phenomenon, the daub on the thermal insulation mortar can reduce the heat and cold on the outside of beam bridge. Hot summer and cold winter area is a transitional region, its exterior wall thermal insulation demand is relatively lower in summer and cold winters.


温度气候的影响下,一般情况下,保温砂浆保温隔热性能能够满足国家对这个地区建筑节能的规定,再加上保温砂浆施工方便、价格低廉,深受施工单位和投资方的欢迎,因此,在这个地区保温砂浆运用较广。夏热冬热地区属于南方地区,由于日照时间长而且强烈,外墙保温不宜采用有机保温材料,在这个地区运用保温砂浆主要考虑改善其保温隔热效果。

Temperature under the influence of climate, in general, heat preservation and heat insulation performance of insulation mortar can meet the provisions of the state of building energy conservation in this area, combined with thermal insulation mortar construction is convenient, the price is low, is popular among construction units and the investor, as a result, thermal insulation mortar used widely in this area. Belong to the south, in the area with hot summer and winter heat because of the sunshine time is long and strong, exterior wall thermal insulation is unfavorable use organic heat preservation material, using thermal insulation mortar main consideration in this area to improve its heat preservation and heat insulation effect.
