Description
技术领域：
本发明涉及建筑材料，具体涉及砌筑墙体的保温砌块。
背景技术：
随着社会进步，节约能源已成为共识。为了节约土地和能源，提高建筑物的保温、隔热功能，混凝土小型空心砌块已被广泛地应用于墙体砌筑中。近些年，为了进一步增强砌块的保温效果，在砌块的空心中部孔中充填聚苯乙烯泡沫塑料保温材料，用这种砌块砌筑墙体，其保温、隔音、防潮效果都得到了大大增强。但这种砌块在制备过程中工人的劳动强度大(人工向砌块预留孔中填保温材料)，同时，因要在空洞中填充保温材料，砌块的体积较大，给墙体砌筑带来不便。
发明内容：
本发明要解决的技术问题是提供一种轻质保温砌块，体积小、重量轻、制造方便、保温效果好。
本发明通过以下技术方案实现：
一种轻质节能保温砖，其特征在于由下列重量份原料，经搅拌混合、挤压成型、养护后制得，所述原料为：低热量粗渣20-40份，粉煤灰20-30份，脱硫石膏5-20份，保温陶粒10-30份，木质纤维素1-5份，水泥10-20份，石英砂5-15份，水适量。
本发明所述原料重量份进一步优选为：低热量粗渣25-35份，粉煤灰23-27份，脱硫石膏10-15份，保温陶粒20-25份，木质纤维素3-4份，水泥13-17份，石英砂8-12份，水适量。
所述低热量粗渣优选为沸腾炉的煤渣。
本发明的原料配比设计，本着在不影响产品的强度和保温性能的情况下，尽可能多的利用工业下脚料，化废为宝，实现可持续发展，因此将低热量粗渣取为25-35份，粉煤灰取为23-27份。
本发明以脱硫石膏作为粘结剂，其配比为10-15份。脱硫石膏的粘结性能增强，如果配比过高，则会影响成型时的脱模(造成粘接)，如果低于10份，由于本发明使用的低热量粗渣、粉煤灰较多，则会造成产品结构松散，不容易成型，增加次品率。
本轻质节能保温砖规格为240×115×90mm(及以下规格)，根据Q\320801HHB001-2008标准，对240×115×90mm规格的保温砖性能指标进行测试，其传热阻值(m2.K)/W平均值为0.97，抗压强度平均值为11.2(强度等级MPa，标准规定平均值≥10)；干燥收缩率(％)平均值为0.025(标准规定平均值≤0.045)；抗冻性(％)其中的强度损失、质量损失平均值分别为10.4、2.4(标准规定平均值分别为≤25、≤5)。本轻质节能保温砖适用于承重墙、以及非承重墙的砌筑。
本发明具有以下优点：
一、本发明的轻质节能保温砖，加入的保温陶粒，具有强度高、容重轻，导热系数低，是生产轻质、保温混凝土的优质骨料，由于其存有封闭的微小气孔，对水结冰产生的膨胀能起缓冲作用，经振动、挤压成型，结构密实，其抗冻性和干燥收缩率大大优于普通混凝土砌块。加入木质纤维素作为保温辅料，由于木质纤维素质轻，而且疏松多孔，具有优良的吸热保温作用。
二、本轻质节能保温砖经测试传热阻值(m2.K)/W平均值为0.97，用于节能建筑外围护结构的承重和非承重结构的墙体，可满足寒冷地区和夏热冬冷地区节能50％的节能建筑要求，可免去外墙的保温处理。与混凝土空心砌块砌筑的墙体相比，每平方米可节约造价30元。
三、由于本产品体积小、重量轻，生产、施工过程中可以大大的减轻劳动者的工作强度，而且产品的规格尺寸与传统的多孔砖一致，图纸设计、工程施工方便。
具体实施方式：
实施例1。
取沸腾炉的煤渣28份，粉煤灰25份，脱硫石膏12份，保温陶粒22份，木质纤维素3份，水泥15份，石英砂10份，适量水(根据原料含水量而定，加入水后搅拌混合好的物料手抓握成团，松手后不散开)，投入搅拌容器内，搅拌5-8分钟，然后将经搅拌混合好的物料，用机械输送至砌块成型机挤压成型，再用机械将挤压成型后的砌块转运到室内的静养保养架上，养护11-13小时，再将砌块转运到室外，并用遮阳网覆盖保湿170小时左右后，继续保养26-29天，即可经检验出厂。
实施例2
取沸腾炉的煤渣30份，粉煤灰26份，脱硫石膏13份，保温陶粒23份，木质纤维素4份，水泥16份，石英砂11份，水适量。
