The use of cement mortar in construction projects, one foundation and masonry wall, used as a binder massive masonry materials, such as masonry rubble, brick use cement mortar; the second is used for interior and exterior plaster ash. In the outside wall works mainly used in building wall leakage prominent direct impact on the quality of construction, but also affected the generation of leakage function of the building, on the interior causing mildew off the impact of the building use. And in addition to these leaks produce masonry wall, the wall is not standardized paving, window sills and other detail engineering process node configuration caused unreasonable, the wall that is the external walls of decorative layer cracking mortar cracking is caused by leakage of primary One reason, great danger. Our view of the current situation on the cement market, developed into a bentonite cement mortar: a bentonite mud has good permeability and allows the incorporation of mortar after mortar becomes full smooth; bentonite significantly improve the mortar with water retention effect cellulose ethers used to improve water retention, while improving workability of mortar, mortar becomes smooth sticking knife, construction convenient; some produce dry mortar customers like the selection of high viscosity cellulose ether that the viscosity high water retention rate, the better, longer opening hours. In fact the high viscosity cellulose ethers with the added amount of open time will reach a maximum, after they dropped because the cellulose ether will crust on the surface, the impact of opening hours. After the compressive strength of mortar with bentonite improved; in fact external insulation mortar compressive strength requirement is very low, but too easy to crack under pressure; shrink mortar with bentonite were more than ordinary mortar, and with bentonite Content and age increases, the contraction increases.
