Problems solved by technology

[0003] When using mortar to build walls, plaster floors, and plaster walls, the fluidity of the mortar will have a great impact on the above operations. If the fluidity is too large, although it can make the operation easier, it will cause a decrease in strength; and if the fluidity If the resistance is too small, although the strength is improved to a certain extent, it will cause the overall mortar to be relatively viscous and difficult to operate

Embodiment 1

[0049] Example 1: A mortar, wherein the components and their corresponding parts by weight are shown in Table 1. The mixture includes three materials: fly ash, admixture HT-TSA, and admixture HT-WRB. During construction, the mixing ratio of cement, sand, admixture, and water is cement, sand, admixture, and water. 1:7.37:0.89:0.97, the fineness modulus of sand is 2.7. And the mortar is prepared through the following steps:

[0050] S1, adding the admixture HT-TSA and the admixture HT-WRB into the water and mixing uniformly to form a first mixture;

[0051] S2, fully mixing cement, sand and fly ash to form a second mixture;

[0052] S3: The first mixture obtained in step S1 is slowly added to the second mixture obtained in step S2, and the mixture is fully stirred and mixed to prepare.

[0054]

Embodiment 2

[0055] Example 2: A mortar. The difference from Example 1 is that the components and their corresponding parts by weight are shown in Table 1. The mixing ratio of cement, sand, admixture, and water is 1:5.27:0.43 : 0.76.

Embodiment 3

[0056] Example 3: A mortar, which is different from Example 1 in that the components and their corresponding parts by weight are shown in Table 1. The mixing ratio of cement, sand, admixture, and water is 1:5.08:0.27 : 0.65.

Abstract

The invention discloses a mortar which contains the following components in parts by weight: 170-260 parts of cement, 1290-1320 parts of sand, 76.65-166.95 parts of mixed material and 170-185 parts of water; the fineness modulus of the sand is 2.5-2.7; the mixing ratio of cement to sand to mixed material to water is 1:(5.08-7.37):(0.27-0.89):(0.65-0.97); the mixed material contains at least one of coal ash, additive HT-TSA and additive HT-WRB. The mortar has the advantages of excellent liquidity and higher pressing resistance after final setting.

Description

Technical field [0001] The invention relates to the technical field of concrete, and more specifically, it relates to a mortar. Background technique [0002] Mortar refers to the bonding material used in building bricks, which is made by adding water to a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.), also called mortar or mortar. [0003] When using mortar to build walls, wipe the ground, and wipe walls, the fluidity of the mortar will have a greater impact on the above operations. If the fluidity is too large, although the operation can be easier, it will reduce the strength; Too small, although the strength is improved to a certain extent, it will cause the overall mortar to be relatively viscous and difficult to handle. Therefore, a mortar with good fluidity and higher compressive strength after final setting has certain commercial value. Summary of the invention [0004] In view of the deficiencies in the prior art, the purpose of the pre...
