A kind of inorganic finishing mortar with steel slag as main raw material and preparation method thereof

Abstract

The invention relates to the field of building materials and in particular relates to inorganic facing mortar taking steel slag as a main raw material and a preparation method of inorganic facing mortar. According to the inorganic facing mortar by taking steel slag as the main raw material, the inorganic facing mortar comprises the following raw material components in parts by weight: 45-55 parts of steel slag sand, 25-30 parts of steel slag powder, 15-20 parts of cement, 1.5-4 parts of acrylic acid dispersible emulsion powder, 0.3-1.0 part of organic silicon water repellent, 0.2-0.5 parts of hydroxypropyl methyl cellulose ether and a proper amount of water. The steel slag serves as the raw material of the facing mortar, and the policy requirements of national green ecological building materials are met. Moreover, the inorganic facing mortar is an environment-friendly product, exploitation and utilization of natural resources are avoided, high additional value utilization of waste steel slag resources is improved, and double benefits are achieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an inorganic decorative mortar with steel slag as the main raw material and a preparation method thereof. Background technique [0002] Steel slag is the waste slag of the steelmaking industry, and its emission is about 10%-20% of the steel output. The iron and steel industry is one of the main pillar industries in our country. In recent years, our country has entered the peak period of construction. The annual steel output has reached more than 400 million tons, and it is showing a continuous increase trend. This means that while the steel production, the annual Forty million to eighty million tons of steel slag will be produced, and a large amount of untreated steel slag has been piled up for many years, occupying nearly tens of thousands of acres of land. At present, the utilization rate of steel slag in my country is much lower than that of fly ash and slag, and it is mostl...

Problems solved by technology

As far as our country is concerned, the steel slag accumulated for many years has become a hazard to the environment. Its stacking not only takes up a lot of valuable land resources, but also affects the quality of groundwater and the growth of plants because there are many alkaline substances such as f-CaO in steel slag. It has caused considerable harm and also caused great pollution to the surrounding environment.
