GRC構(gòu)件產(chǎn)品質(zhì)量的重要規(guī)范是就是要看水泥強(qiáng)度，一起它也是區(qū)分水泥標(biāo)號(hào)的重要依據(jù)。水泥強(qiáng)度是指水泥膠砂漿硬化試體所能接受外力損壞的才能，用Map表明，它是水泥重要物理性能之一。水泥強(qiáng)度分三種：抗壓、抗折、抗拉強(qiáng)度，均指水泥膠砂硬化試體接受壓縮損壞、曲折損壞、拉伸損壞時(shí)的大應(yīng)力。
An important criterion for the quality of GRC components is the strength of cement, which is also an important basis for distinguishing cement grades. Cement strength refers to the ability of cement mortar hardened specimen to accept external force damage. It is shown by map that it is one of the important physical properties of cement. There are three kinds of cement strength: compressive strength, flexural strength and tensile strength, all of which refer to the large stress when the cement mortar hardening specimen is subjected to compression damage, zigzag damage and tensile damage.
GRC構(gòu)件的強(qiáng)度除取決于水泥強(qiáng)度外，一起還取決于單件外表尺度及填料比，裝備不同的筋骨支撐結(jié)構(gòu)所決議的。GRC是原絲抗堿纖維短切后同配有添加劑的砂漿一起通過(guò)噴發(fā)設(shè)備噴發(fā)入模，然后逐層滾壓成型，特別表現(xiàn)GRC構(gòu)件合不合格的首要目標(biāo)為纖維含量有無(wú)5%左右，往常鋪網(wǎng)格布的GRC構(gòu)件1%的纖維量都沒(méi)有。
The strength of GRC members depends not only on the strength of cement, but also on the external dimension and filling ratio of single member, which is determined by different rib support structures. GRC is a kind of alkali resistant fiber, which is chopped and sprayed into the mold together with the mortar with additives through the eruption equipment, and then rolled layer by layer. In particular, the primary goal of GRC component is whether the fiber content is about 5%, and the fiber content of GRC component with mesh cloth is not about 1%.
1、GRC裝飾線條是氣密性膠凝資料，因而有必要具有相應(yīng)的厚度，使分子間親合力抵達(dá)zui佳，然后確保必定的運(yùn)用年限并在運(yùn)用期內(nèi)堅(jiān)持無(wú)缺，質(zhì)量好的均勻厚度應(yīng)在8毫米以上。假設(shè)過(guò)薄，不只運(yùn)用年限短，功用差，并且在運(yùn)送及設(shè)備過(guò)程中的破損率較大。
1. GRC decorative lines are airtight gelling materials, so it is necessary to have the corresponding thickness to make the intermolecular affinity reach Zui, and then ensure a certain service life and adhere to no shortage during the service life. The uniform thickness with good quality should be more than 8 mm. If it is too thin, not only the service life is short, the safety function is poor, but also the damage rate in the process of transportation and equipment is large.
2、現(xiàn)在市場(chǎng)上的部分GRC裝飾線條產(chǎn)品，因廠家片面追求獲利，選用將邊緣做厚而中心做薄的方法，詐騙消費(fèi)者。像這樣的GRC裝飾線條有兩種區(qū)別辦法：一是分量區(qū)別，一根寬10厘米、長(zhǎng)2.44米的標(biāo)準(zhǔn)分量小于2.3公斤，不同長(zhǎng)度的可按此份額來(lái)核算;二是看鋸斷截面的厚度是否抵達(dá)8毫米。
2. Now some GRC decorative line products on the market, because the manufacturers pursue profit unilaterally, choose the method of making the edge thick and the center thin to cheat consumers. There are two ways to distinguish GRC decorative lines like this: one is the weight difference, a standard weight of 10 cm wide and 2.44 m long is less than 2.3 kg, and different lengths can be calculated according to this share; the other is to see whether the thickness of the sawing section reaches 8 mm.
3、GRC裝飾線條多為空心，這樣確保了自重小、設(shè)備便利的特征，而15、20mm的壁厚，加以其間的尼龍網(wǎng)片，確保其全體剛性和堅(jiān)韌性，全體剛性易于確保線條效果不發(fā)生較大變形，而堅(jiān)韌性則使之更像強(qiáng)度、剛度全體微縮的鋼筋混凝土。在究竟損壞時(shí)，構(gòu)成若干塑性鉸，不致俄然開(kāi)裂，構(gòu)成人員損害和建筑物自身?yè)p壞;一起，因?yàn)槠湓O(shè)備便利的特征，與抹灰等其他裝飾分項(xiàng)工程比較，具有縮短全體全體工期、不受時(shí)節(jié)、氣候、氣溫狀況等外部條件影響的長(zhǎng)處。
3. GRC decorative lines are mostly hollow, which ensures the characteristics of small self weight and convenient equipment. The wall thickness of 15 and 20 mm, together with nylon mesh between them, ensures the overall rigidity and tenacity. The overall rigidity is easy to ensure that the line effect does not have large deformation, while the tenacity makes it more like the reinforced concrete with the overall shrinkage of strength and rigidity. When it is damaged, it forms a number of plastic hinges, which will not cause sudden cracking, personnel damage and building damage; together, because of its convenient equipment, compared with plastering and other decoration sub projects, it has the advantages of shortening the whole construction period and not affected by external conditions such as season, climate and temperature.
