Thermal-insulation fireproof light mortar and preparation method thereof
The invention belongs to the field of building materials, and relates to thermal-insulation fireproof light mortar and a preparation method thereof. The method comprises the following steps of: treating low-grade limestone to obtain high-calcium lime; and mixing the high-calcium lime with vitrified fine sand, modified shell powder and cement to prepare the thermal-insulation and fireproof light mortar. After the mortar is used as plastering mortar, a flat surface and a vertical surface can reach 3mm or below, gypsum plastering is not needed; the heat conductivity coefficient of the mortar reaches 0.73 W/m <2>.K; the mortar has good thermal insulation effect and good fire resistance and enables the compressive strength of a wall surface to reach 20MPa; and the mortar can be used as thin-layer masonry mortar and also can be used as plastering mortar.
本发明属于建筑材料领域，具体涉及一种保温耐火轻质砂浆及其制备方法；通过对低品级石灰石进行处理得到高钙石灰，与玻璃化细砂、改性贝壳粉和水泥混合制成一种保温耐火轻质砂浆，使其作为抹面砂浆后，平整面和垂直面可以达到3mm以下，无需再进行石膏抹灰，导热系数达到0.73W/m2·k，保温效果好，耐火性好，可使墙面的抗压强度达到20MPa，除可作为薄层砌筑砂浆外，还可作为抹面砂浆。
