Embodiment Construction

[0024] Take 5-10kg of saline-alkali soil and put it into a muffle furnace, raise the temperature to 900°C, and burn it for 2-4 hours to obtain dry saline-alkali soil; take 2-4kg of dry saline-alkali soil, 10-20kg of limestone, 2-4kg of powder Coal ash, 1-2kg of phosphogypsum and 1-2kg of fluorogypsum were mixed, crushed and ground to obtain mixture A; 4-8kg of slag and 2-4kg of silica fume were mixed and crushed, then put into a ball mill for grinding to obtain mixture B; Take 15~30kg of mixture A and 5~10kg of mixture B, mix and stir, crush and grind again to obtain raw meal; put the raw meal into a high-temperature furnace at 900°C, preheat for 30 minutes, and then raise the temperature of the high-temperature furnace at a rate of 10°C / min Calcined at 1300°C for 1 hour, and then kept warm for 30 minutes to obtain clinker; take out the clinker and cool it, grind the cooled clinker, and pass through a 200-mesh sieve to obtain cement; take 10~20kg of cement, 0.2~0.4kg of sodium ...

Abstract

The invention relates to a producing method of a concrete waterproof material, and belongs to the technical field of concrete preparation. According to the concrete waterproof material prepared by thepreparation method, the surface of concrete is modified in an early stage by a silane modifier to have a hydrophobic surface for ensuring the waterproof performance in the early stage, with the extension of time, when the hydrophobic surface can not meet the waterproof demand, active crystalline material inside the concrete absorbs moisture, grows along concrete gaps, and blocks moisture from entering the concrete, and therefore the concrete waterproof material has long-term effective waterproof effect, and at the same time, due to the reduction of cracks in the concrete, the density of the concrete is increased and the concrete is enhanced. The concrete waterproof material prepared by the preparation method of the invention has a wide source of raw materials, lower cost and long-term excellent waterproof effect.

Description

technical field [0001] The invention relates to a method for preparing a concrete waterproof material, belonging to the field of concrete preparation. Background technique [0002] Concrete is a porous and heterogeneous material, and its porous nature makes concrete highly permeable, and CO in the air 2 , SO 2 Under the joint action of multiple factors such as acid gas, sulfate-like harmful media, and loading, the performance of concrete materials gradually deteriorates and the durability decreases. There are many factors affecting the durability of concrete, and its failure mechanism is also very complicated. However, a large number of studies have shown that the deterioration mechanism of concrete durability problems is mostly related to the existence and migration of water. For example, when water comes into contact with the concrete surface, the concrete Hydrophilicity makes it easy for water to absorb to the surface of the concrete through capillary action, and furthe...
