Abstract

The invention discloses a portland cement refractory mortar and a construction technology thereof. The portland cement refractory mortar comprises the following components in percentage by weight: 12-16% of portland cement, 10-15% of powdery refractory mortar, 5% of silica powder, 20-30% of quartz sand, 30-50% of river sand and the balance of water. The refractory mortar has high early strength, can resist high calcination temperature, has high adhesive property and strength after the calcination and is used for solving the safety problem during the current construction process; and moreover, the cost is lower than that of the conventional refractory castable.

Description

technical field [0001] The invention relates to a refractory mortar and a construction process thereof, in particular to a Portland cement refractory mortar and a construction process thereof, which are used for building refractory bricks. Background technique [0002] The refractory technology of the existing technology is relatively mature, and the micro-powder technology and low-cement technology have been successfully applied to refractory castables, so that the cast refractory structures can work in very harsh high-temperature environments. However, the cost of using refractory castables is often very high. In some working environments that do not have strict requirements on high-temperature environments, using refractory castables for structures will undoubtedly cause waste of functions and increase costs. [0003] At present, some structures that work in the environment of 500 ° C to 1200 ° C, such as the fire wall of the blowout pit in the petroleum industry, indepen...
