Embodiment 1-4

[0045] Embodiment 1-4: the implementation method of waste ceramic powder as high-performance concrete admixture, comprises the steps:

[0046] 1) Configure the corresponding ceramic powder admixture raw materials according to the percentages in Table 4, and the proportion of each material meets the corresponding technical indicators mentioned above.

[0047] Table 4 Admixture raw material percentage (unit: %)

[0048]

[0049]

[0050] Preparation of ceramic powder: Mix all kinds of ceramic waste near the Jingdezhen ceramic workshop and waste ceramic bricks on the construction site according to the ratio in Table 4. The mixed material was crushed, screened, cleaned, dried, and ball milled to make waste ceramic powder, which was then placed in an electric heating furnace, heated at 200°C for 4 hours, and then ground by a cement ball mill for 1 hour. The gradation of ceramic powder particles is continuous and reasonable, and the specific surface area is 350m 2 / kg;

Abstract

The invention discloses a high-performance concrete admixture in use of waste ceramic powder and an implementing method thereof. The high-performance concrete admixture is prepared by the following steps: utilizing waste ceramics as a main material and utilizing active seed crystals and a modified enhancer as auxiliary materials; performing modified treatment and high-temperature smelting on various materials, then putting into a cement mill to mill the materials to be pre-finished products with specific area of 300-450 m2/kg, and finally, doping mixed fibers. The high-performance concrete admixture comprises the raw materials in parts by weight: 80-100 parts of waste ceramic powder, 6-9 parts of active seed crystal, 2-6 parts of modified enhancer and 5-10 parts of mixed fibers. By adopting mixed ceramic powder, density of cement mortar is effectively increased; strength of concrete is improved and durability of concrete is remarkably improved. Energy problems are solved, and meanwhile, an environmental protection purpose is considered; the high-performance concrete admixture has remarkable technical, economic and social benefits.

Description

technical field [0001] The invention belongs to building materials, and in particular relates to an admixture for preparing high-performance concrete and an implementation method thereof. Background technique [0002] Looking at the current research status of all new admixtures and the durability of concrete, the analysis from all angles is comprehensive and in place. Whether it is from the macroscopic physical and mechanical properties or the microscopic properties of the material itself, countless domestic and foreign scholars have conducted detailed research, discussion and analysis on concrete, including new concrete. The experimental research on ordinary concrete and conventional admixture concrete has been relatively mature, and it has a good theoretical and practical basis in terms of preparation technology and performance improvement. There are also many studies on new admixture concrete, but a systematic research summary is lacking. The research on a new type of a...
