We are offering high quality refractory mortar cement.Introductionrefractory mortar is also as known as joint filler, it is composed of a certain particle ratio of refractory powder, binder and additive, pour water or liquid binder to tune into a paste. Silica mortar is an important part of refractory mortar which is as cab-o-sil or adding some ganister sand as main raw materials, the binder adopts mild-clay or chemical bond.Advantage :1.high adhesive strength.2.high refractoriness.3.excellent refractoriness under load.4.good installation performance.Specifications :items silica refractory mortarrefractoriness ( c) 1580 1670 1690 1670 1690 1690 1710 1710bonding time(min) 1-2 1-2 1-2 1-2 1-2 1-2 1-2 1-2chemicalcomposing(%) sio2 85 92 94 92 94 94 94 96al2o3 - - 1 - - 1 0.5 0.8fe2o3 - - - - - 1 0.5 0.7flexural bond strength(mpa) 110c24h 1 1 1 0.5 0.5 0.8 - 0.81400c3h 3 3 3 1.5 1.5 2 - 0.50.2mparefractorinessunderload(c) 1420 1500 1600 - - 1600 1650 1620applications :silica mortar is mainly used for laying and repair of coke oven, hot blast stove, glass melting furnace, melting furnace and other masonry of high quality silica bricks industrial furnace.Mixing sequence:1. The silica mortar is the fine powder (0.088mm). Put the mortar in to the mixer and spray the small bag of additives on the dry powder evenly, mix them for 3 to 5min. Next, put 32 to 35 per cent of clean water (tap water and water amount can be adjusted according to actual conditions) into it and continue mixing for 5 to 10min. The effect will be better if you put the mortar slurry static for 10min. Amount of agitation should be determined according to the capacity of mixer. But it must be used by the bag.
