Multifunctional environment-friendly mortar modified by optimizing basalt admixture system and preparation method of multifunctional environment-friendly mortar

Abstract

The invention relates to multifunctional environment-friendly mortar modified by optimizing a basalt admixture system. The multifunctional environment-friendly mortar comprises the basalt admixture system consisting of the fine basalt powder, fine basalt sand and basalt fiber, cement or alkali activator and water. The dry powder of the mortar is 100 parts by mass and comprises the following components in parts by mass: 1) 10-40 parts of the cement or alkali activator, 2) 10-40 parts of the fine basalt powder and 3) 30-50 parts of the fine basalt sand. Besides the dry powder, the basalt fiber accounts for 0-5 parts by mass and water accounts for 5-20 parts by mass. The invention further provides a preparation method of the multifunctional environment-friendly mortar modified by optimizing the basalt admixture system. The basalt admixture is doped into a material system of cement mortar, so the preparation energy consumption of the high-strength cement mortar is reduced, the working performance of the mortar is improved, and the application field of the high-strength cement mortar is expanded to the civil engineering material fields of national defense electromagnetic protection engineering, water conservancy engineering, fire-resistant construction engineering and the like.

Description

technical field [0001] The invention belongs to the fields of building materials, water conservancy projects and basic engineering construction, and relates to a multifunctional low-cost environmental protection mortar material modified by optimizing the basalt admixture system and a preparation method thereof. Background technique [0002] Due to better mechanical properties, high-strength cement mortar—as a kind of fine aggregate concrete—is gradually entering the stage of engineering application. However, the large amount of cement and poor flow properties are restricting the engineering application of high-strength cement mortar. At the same time, with the rise of the concept of green environmental protection, reducing the energy consumption of building materials has become a new topic in the building materials industry. How to save the amount of cement and improve the fluidity of high-strength cement mortar at low cost, and at the same time reduce the energy consumption...
