Embodiment Construction

[0044] The present invention is a kind of mortar used for building firewalls in the petroleum industry, which comprises the following components: the raw materials are composed of 15-25% of high alumina cement, 2-5% of powdery refractory mud, and 15-5% of bauxite particles. 25%, dry sand 50-60%, and the balance is water. When the temperature is low, you can add early-strength agent or early-strength superplasticizer with a mass percentage of 0.5-2%. The maximum particle size of bauxite particles is less than 5mm, the dry sand is continuously graded medium sand, when the high-alumina cement is selected as 425 type, the dosage is 20-25%, when the high-alumina cement is selected as 525 type, the dosage is 17-25%, the high-alumina cement When choosing the 625 type, the dosage is 17-22%, and when the high-alumina cement is choosing the 725 type, the dosage is 15-20%.

Abstract

The invention relates to a mortar used for building a firewall in petroleum industry, which comprises the following ingredient by mass percentage 15-25% of alumina cement, 2-5% of powdery fire clay, 15-25% of bauxite particle, 50-60 parts of dry sand and the balance of water. The mortar of the invention is capable of effectively raising the intensity of the mortar at early stage, increasing the bonding performance of the mortar and firebricks, ensuring the intensity of the mortar after high temperature calcining, and enhancing the corrosivity resistance of sulfate; and invention has the advantages that the preparation process and the construction process are convenient to operate, the construction period can not be prolonged, no other side-effect and hidden trouble can be generated, and is suitable for projects with short construction period and immediate usage, thereby the construction risk can be effectively reduced and the hidden trouble can be eliminated, compared with a traditional process, the cost of the invention is lower.

Description

technical field [0001] The invention relates to a mortar used for building refractory bricks and a construction process thereof, in particular to a mortar used for building a firewall in the oil industry and a construction process thereof. Background technique [0002] Refractory cement is a powder made of bauxite clinker and a binder. It is used as a filling material for the gap between refractory bricks. Refractory cement is also called bauxite cement. It is water with low alkalinity aluminate as the main mineral The hard material is an unshaped refractory material. Bauxite, also known as bauxite or high alumina, is mainly composed of aluminum oxide; it is brown or light red due to iron content, with a density of 3.9-4q / cm3 and a hardness of 1-3; it is opaque, brittle, and insoluble in water. It is mainly used for aluminum or refractory materials. Refractory brick is a shaped refractory material, which is used to build firewalls or furnaces, and the content of aluminum o...
