Description

一种不易离析的湿拌砂浆
技术领域
本发明涉及湿拌砂浆技术领域，尤其涉及一种不易离析的湿拌砂浆。
背景技术
普通现场拌制砂浆是由水泥、河砂、清水拌合，经硬化起到将建筑材料粘结一体，形成坚固整体的作用。随着建筑业技术进步和文明施工要求的提高，现场拌制砂浆日益显示出其固有的缺陷，如砂浆质量不稳定、材料浪费大、砂浆品种单一、文明施工程度低以及污染环境等。
湿拌砂浆是指用于建设工程中的各种砂浆拌合物，是当今较为主要的工程原料之一。湿拌砂浆具有价格低廉、生产工艺简单、施工方便等特点，因而使用量越来越大。但湿拌砂浆存在易离析的缺陷，成为目前需要解决的技术问题。
发明内容
基于背景技术存在的技术问题，本发明提出了一种不易离析的湿拌砂浆，原料来源广，成本低，浆存放时间可以达到48h以上，完全适应砂浆的工程应用特点，能保证必要的工作时间，砂浆的稳定性好，在运输储放过程中不易离析，在我国建筑节能应用领域具有极大的市场空间和发展前景。
本发明提出的一种不易离析的湿拌砂浆，其原料按重量份包括：硅酸盐水泥30-50份，煤渣25-35份，破碎鹅卵石100-140份，减水剂1-2份，水35-45份，椰油酰胺丙基甜菜碱1-2份，中空玻璃微珠5-15份，聚丙烯腈纤维5-15份。
优选地，硅酸盐水泥、煤渣、破碎鹅卵石的重量比为35-45：28-32：110-130。
优选地，沥青颗粒、椰油酰胺丙基甜菜碱、中空玻璃微珠、聚丙烯腈纤维的重量比为2-6：1.2-1.8：8-12：5-15。
本发明允许存放时间可以达到48h以上，完全适应砂浆的工程应用特点，能保证必要的工作时间，砂浆的稳定性好，在运输储放过程中不易离析，原料来源广，成本低，在我国建筑节能应用领域具有极大的市场空间和发展前景。
本发明采用沥青颗粒与椰油酰胺丙基甜菜碱、中空玻璃微珠、聚丙烯腈纤维配合，可减少小尺寸物料的缺失，改善浆体的流动性，有利于硅酸盐水泥、煤渣、破碎鹅卵石的分散，不易沉降，便于运输。
本发明所得湿拌砂浆的抗压强度为38-45MPa，在相对湿度60±5％的养护条件下28d干燥收缩低于1200με，可用于不同强度等级要求的工程应用场合，提高了材料的工程应用领域，具有十分重要的现实意义。
