Abstract

The invention discloses high-strength environment-friendly light-transmission cement mortar composed of a cement-based grouting material and optical fibers, wherein the cement-based grouting material comprises the following components in parts by weight: 30-50 parts of aluminum sulfate salt cement, 60-80 parts of natural sand, 10-20 parts of a mineral powder, 5-7 parts of metakaolin, 3-6 parts of a medical stone powder, 2-3 parts of nitrogen doped titanium dioxide, 0.8-1.2 parts of calcium nitrate, 1-1.5 parts of sodium acetate, 2-3 parts of an inner curing agent, 1-2 parts of a water reducing agent, 1-2 parts of a defoaming agent, and 40-60 parts of water; the optical fibers are PMMA plastic lighting optical fibers with the diameter of 0.5 mm, the surface is coated with a polytetrafluoroethylene film, and the distance between the optical fibers is 3-4 mm. The prepared light-transmission cement mortar has the advantages of good light transmission performance, high flexural and compressive strength, large toughness, and excellent crack resistance; and the preparation method is simple, has no toxic substance released in the preparation process, and is economic and environmentally friendly.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a high-strength, environment-friendly, light-transmitting cement mortar. Background technique: [0002] The building structure is the main skeleton of the building, and the material basis of the structure is the building material. The optimization and development of building structures continuously promote the renewal and development of building materials. Concrete is the most widely used building material in modern times, and it is also the largest man-made material at present. Since the beginning of the 20th century, engineering structures using concrete as building materials have developed rapidly. Compared with other building materials, concrete has become the first choice for modern symbols such as buildings, bridges, dams, highways and urban transportation systems due to its good comprehensive performance. Material. According to incomplete statistics, the amount of con...
