Embodiment 1

[0034] Example 1: Preparation of environment-friendly color tile grout

[0035] Table 1 (units are mass percentage%)

[0036]

[0037] Note: 100-400 mesh heavy calcium powder can be 100 mesh heavy calcium powder, 200 mesh heavy calcium powder, 300 mesh heavy calcium powder, 400 mesh heavy calcium powder. All can realize the present invention.

[0038] Weigh each component according to the formula in Table 1, and stir evenly. Add water accounting for 20% of the mass of the powder into the bucket, and mechanically stir while adding the above powder. After stirring into a putty shape, let it stand for 10 minutes to mature, and then mechanically stir for 30 seconds, then it can be used. Due to the fast curing speed of the caulking agent and the short opening time, it is recommended to use it up within 30 minutes after stirring once.

Embodiment 2

[0039] Embodiment 2 Effect experiment

[0040] According to the "Cement mortar strength test method (ISO method)" (GB / T 17671-1999), the test method for the compressive and flexural strength of cement mortar.

[0041] Table 2

[0042] group Flexural strength Compressive strength 1 5.3 27.5 2 6.3 30.6 3 7.2 38.4 4 6.0 28.6 5 5.8 27.8 6 5.0 30.1

[0043] It can be seen from the results in Table 2 that the ceramic tile grout with steel slag powder is tightly bonded to the tiles without cracking. Steel slag powder tile grout has high strength and good working performance.

Abstract

The invention provides a composition and its preparation method and use. The composition comprises, by weight, 35 to 40% of white cement, 45 to 50% of steel slag powder, 10 to 15% of heavy calcium powder, 0.1% of a water repellent, 0.15% of a water-retaining agent, 0.4% of lignin fibers, 1% of re-dispersible latex powder and 0.075 to 0.25% of a water reducer. The invention discloses the preparation method of the composition and a use of the composition as a tile-seam filling agent. The composition can reduces use amounts of an iron oxide pigment and cement, utilizes industrial by-products, realizes resource comprehensive utilization, is environmentally friendly, utilizes wastes, improves tile-seam filling agent workability, improves early-stage and later-stage strength of the tile-seam filling agent, reduces shrinkage cracks of the tile-seam filling agent in later-stage curing, and improves peaceability, application properties and thermal adaptability of a cement mortar system.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a composition using steel slag powder as a filler, and also relates to a preparation method of the composition and an application of the composition in construction engineering. Background technique [0002] In modern buildings, tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buildings. In order to avoid hollowing between tiles due to thermal expansion and contraction, there must Leave a gap that needs to be filled with tile grout. The main components of tile grout are cementitious materials, fillers and additives. The cementitious materials endow the grout with adhesion, and the additives endow the grout with good construction, flexibility and other functionalities. Existing tile grouts use inert materials such as fine sand or heavy calcium powder as fillers, which do not react with ceme...
