Embodiment 3

[0060] Change the clay that crossed 100 mesh sieves into 50 parts in the raw material, and other steps are identical with embodiment 1.

[0061] The test results are as follows: the initial setting time is 17 hours, the shrinkage rate is 2.08%; the flexural strength at 28 days is 0.82MPa, and the compressive strength is 2.21MPa; with continued maintenance, the compressive strength at 3 months is 2.76MPa. The appearance of the test block is similar to that of traditional composite soil.

Abstract

The invention discloses sweet rice tabia for perfusion. The sweet rice tabia is composed of raw materials, by weight, 100 parts of calcium hydrate powder, 5-20 parts of metakaolin, 2-10 parts of pregelatinization sweet rice flour, 0.5-1.5 parts of water reducer, 200-400 parts of yellow sands, 10-100 parts of clay, and 50-140 parts of water, or 10-100 parts of clay in the raw materials is changed to 10-250 parts of brick powder, or 10-100 parts of clay in the raw materials is changed to 10-75 parts of clay and 10-200 parts of brick powder. The provided sweet rice tabia for perfusion solves the problems that for traditional sweet rice tabia, the preparation technology is complex, solidification is slow, contraction is large and the intensity is low, and a grouting reinforcement material new product is provided for protection and maintenance of tabia buildings.

Description

technical field [0001] The invention relates to the technical field of building materials and cultural relics protection, in particular to a glutinous rice compound soil for pouring and a preparation method thereof. Background technique [0002] Sanhe clay is a very widely used building material in ancient China. It has the advantages of good durability, high self-strength and bonding strength, strong toughness, and good seepage resistance. excellent. Judging from the existing architectural remains and archaeological results, Sanhe clay was mainly used in important facilities such as building foundations, grounds, burials, water conservancy projects, and forts in ancient times. [0003] A large number of ancient triad building sites left over to the present are precious cultural relics and have important historical value. However, in the current practice of protection and restoration of ancient buildings, people habitually use cement-based mortar or hydraulic lime as reinfo...
