industry market background
Self - gelling or auxiliary gelling material
Self-cementing or auxiliary cementing materials can replace or save M series masonry cement, PC series composite Portland cement, etc., widely used in a variety of industrial and civil building materials.
Market Background
The State Council issued the Guiding Opinions on Promoting the Construction of sponge cities, requiring that more than 80 percent of sponge cities be built nationwide by 2030.
- The construction of sponge city needs a lot of inorganic permeable water storage materials.
- Coal based solid waste is the main raw material of inorganic permeable water storage materials.
- The national demand for inorganic permeable water storage materials is 5.3 billion m³.
- The market demand is 300 billion.

Innovative Technological Ideas to Fill The Gaps
Raw Material
Steel slag powder + fly ash raw material + desulfurization gypsum, 100% solid waste.
Process Equipment
Mechanical hole-making - static forming + hydrothermal curing
Product Performance
High strength + high water permeability + high abrasion resistance + anti-clogging + freeze-thaw resistance.
Application of Self - gelling or Auxiliary Gelling Material
Since the gel or auxiliary cementitious materials can replace or save M series masonry cement, PC series composite Portland cement and so on, are widely used in industrial and civil architecture really stone paint (instead of some organic emulsion), putty powder, masonry and plastering mortar, bedding and backfill concrete, wall materials and fabricated parts, brick block, inorganic stone slab (instead of natural stone, artificial stone, brick of pottery and porcelain, etc.), stone series, all kinds of PC components, etc. In particular, it can be prepared into a variety of prefabricated building materials and sponge city water permeable materials, ultra-thin and high strength inorganic stone plates (instead of natural stone and ceramic plates), UHPC ultra-high performance concrete components.
Experimental brick machine made in our own plant
It is superior to the national standard in terms of pore forming rate, static pressure loss, water permeability, etc.
The national standard (GB / T 25993-2010) is implemented. Water cement ratio is 0.2, molding pressure is 20MPa, curing temperature is 20 ℃ and humidity is 98%.
Innovative technology and equipment -- pressure controlled foaming machine
Pressure controlled foaming can significantly improve the strength and achieve “light and high strength”.
- The solid waste-based ultrafine powder is foamed to prepare porous materials, which can be used in building insulation materials, adsorption materials and sound-absorbing materials, etc., and the application prospect is very broad;
- Development direction: “Ultra light, high strength, high toughness, adjustable hole structure”;
- Support prefabricated building materials, with a market capacity of trillions.

Conventional foaming / hot pressing foaming
Product characteristics difference between pressure foaming and conventional foaming
The results show that the pressure foaming test block has relatively independent spherical pores, and the conventional foaming test block has connected irregular pores.
Combination design of permeable material and water storage material
The construction cost can be reduced by 2 / 3, the urban waterlogging problem and urban heat island effect can be effectively solved, and the recycling of urban construction waste can be realized.
- The upper part can pass through and the lower part can keep water, to simplify the construction；
- Permeability coefficient: 0.5cm/s；
- water storage rate: 600kg / m³。
Solid waste composite cementitious putty powder
When the content of steel slag particles reaches 80%, the performance indexes of stone like paint are better than and meet the requirements of national standard. With the increase of steel slag particle content, the bond strength of stone like paint decreases.
- The putty powder is mainly used for indoor and outdoor plastering, and the domestic market is nearly 100 million tons / year.
- The putty powder is mainly composed of natural sand and cement in proportion. The production cost is about 800 yuan / ton, and the market price is 1200-1500 yuan / ton.
- Using industrial solid waste steel slag composite powder instead of cement and natural sand to prepare putty powder can reduce the production cost by 30-50%, and the market capacity is more than 100 billion yuan.
