Embodiment 1

[0031] A highly recognizable red high-strength polymer cement water-resistant mortar. The raw materials used include white cement, metakaolin, latex powder and iron oxide red pigment. The water-binder ratio of the cement mortar is 0.39, and the mortar-sand ratio is 1:1.4. The mass percentages of white cement, metakaolin and latex powder in the material are 89%, 7% and 4% respectively, and the sum of the mass percentages of each component is 100%. The amount of iron oxide red pigment accounts for 1%-7% of the mass of the gelling material. A total of 2 groups were made. Group W used only white cement to make mortar, and Group O made high-resolution red high-strength polymer cement water-resistant mortar mixed with different amounts of iron oxide red pigments.

[0032] The curing method is to put it into a dry curing room for curing for 3 days after demoulding, then move the test block to a standard curing room for curing for 28 days, and finally soak the test block in water for ...

Embodiment 2

[0040] A high-recognition yellow high-strength polymer cement water-resistant mortar. The raw materials used include white cement, metakaolin, latex powder and iron oxide yellow pigment. The water-binder ratio of the cement mortar is 0.39, and the cement-sand ratio is 1:1.4. The mass percentages of white cement, metakaolin and latex powder in the material are 89%, 7% and 4% respectively, and the sum of the mass percentages of each component is 100%. The amount of iron oxide yellow pigment accounts for 5% of the mass of the cementitious material.

[0041] The curing method is to put it into a dry curing room for curing for 3 days after demoulding, then move the test block to a standard curing room for curing for 28 days, and finally soak the test block in water for water resistance test. Use an electronic scale to measure the mass of the test block. According to GB / T17671-1999 "Cement Mortar Strength Test Method", the 3-day, 7-day and 28-day compressive strength of the referen...

Embodiment 3

[0047] A high-recognition green high-strength polymer cement water-resistant mortar. The raw materials used include white cement, metakaolin, latex powder and iron oxide green pigment. The water-binder ratio of the cement mortar is 0.39, and the mortar-sand ratio is 1:1.4. The mass percentages of white cement, metakaolin and latex powder in the material are 89%, 7% and 4% respectively, and the sum of the mass percentages of each component is 100%. The amount of iron oxide green pigment accounts for 5% of the mass of the cementitious material.

[0048] The curing method is to put it into a dry curing room for curing for 3 days after demoulding, then move the test block to a standard curing room for curing for 28 days, and finally soak the test block in water for water resistance test. Use an electronic scale to measure the mass of the test block. According to GB / T17671-1999 "Cement Mortar Strength Test Method", the 3-day, 7-day and 28-day compressive strength of the reference ...

Abstract

The invention discloses colored high-intensity polymer cement water-resistant mortar and a preparation method thereof. The colored high-intensity polymer cement water-resistant mortar is prepared fromthe raw materials of white cement, metakaolin, A / S type latex powder and pigments, wherein a gelling material is prepared from the following ingredients in percentage by mass: 85 to 93 percent of white cement, 4 to 10 percent of metakaolin and 3 to 5 percent of latex powder; the pigments account for 3 to 5 weight percent of the gelling material; the water-to-glue ratio of the mortar is 0.35 to 0.42; the glue-to-sand ratio is 1:(1.1 to 1.7). The high-differentiation-degree high-intensity polymer cement water-resistant mortar has high intensity, good water-resistant performance and high differentiation degree. The preparation process comprising two pre-mixing steps and one blending step can be used for obtaining the uniformly mixed gelling materials and colored sand, so that the structure of the mortar is compact; all ingredients sufficiently achieve the effects; the mortar intensity is higher; the water resistance is better.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a highly recognizable colored high-strength polymer cement water-resistant mortar and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy and the increasing improvement of infrastructure construction, people's standards for construction projects are also constantly improving. In this form, many new problems have been exposed in construction projects. Many properties of traditional building materials have gradually failed to meet people's needs. Require. Engineering leakage is one of the main problems in the current construction engineering field. Building leakage not only affects people's daily life and work, but also the chemical erosion caused by leakage has caused great harm to the performance and durability of buildings, threatening People's property and life safety. In addition, because the ...
