保溫砂漿中的砂子起到什么作用

时间:2016-07-18     作者:www。hdbwsj。com【原创】   阅读

首先:砂子是什么:砂子,多為人工制造,或是從人工從某些石塊上打磨下來的,顆粒相對更大一些,飽滿感更強一些,拿在手中能清晰地感覺到有顆粒存在。

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:砂子有什么樣的應用:1。在混凝土中,能同水泥分子相結合,增加水泥分子的擴散面積,形成水泥漿后,增強水泥的水化作用。2。具有一定的潤滑作用,改善混凝土拌合物的和易性。3。在各類砂漿中起到骨料作用,并可有效地節省膠結材料。4。填充石子顆粒間的空隙,與石子一起共同起到骨架作用,提高混凝土的密實性和強度。5。在水泥水化過程中,有效地降低水泥水化熱,抑制水泥因物理、化學反應體積變化時裂縫的產生。6。可在膨脹土、冰凍土等不良土層中充當墊層,起到了保護作用。

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.


砂子型的保溫砂漿

The sand type thermal insulation mortar


在功能特征上繼承了砂子的一切功能特點,這類類型的保溫砂漿能更好的為建筑工程做出貢獻。砂子型的保溫砂漿應用:我國地域廣闊,南北溫差較大,由于保溫砂漿獨有的特點,在不同地區有不同的作用。夏冷冬冷地區,對建筑外墻保溫要求較高,普通的保溫砂漿很難滿足要求。由于有機保溫材料的保溫效果較好,因此,在這些地方一般采用此種材料進行外墻保溫。但是由于外墻墻體材料和混凝土梁柱的導熱系數不同,易產生冷熱橋現象,此時在梁柱外側涂抹上保溫砂漿可以減少冷熱橋的產生。夏熱冬冷地區是一個過渡地區,其外墻保溫要求較夏冷冬冷地區要低一些。

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。


溫度氣候的影響下,一般情況下,保溫砂漿保溫隔熱性能能夠滿足國家對這個地區建筑節能的規定,再加上保溫砂漿施工方便、價格低廉,深受施工單位和投資方的歡迎,因此,在這個地區保溫砂漿運用較廣。夏熱冬熱地區屬于南方地區,由于日照時間長而且強烈,外墻保溫不宜采用有機保溫材料,在這個地區運用保溫砂漿主要考慮改善其保溫隔熱效果。

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.
