Embodiment Construction

[0033] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific construction unit, and the unspecified implementation conditions are usually the conditions in routine experiments.

[0034] Embodiment of the technical solution:

[0035] Magnesium phosphate cement-based materials are generally divided into magnesium phosphate cement slurry, magnesium phosphate cement mortar, magnesium phosphate cement concrete, and fiber magnesium phosphate cement-based composite materials. The applicant has verified by experiments that the feasible order of stirring and feeding is: (a) the retarder component dissolves (water and composite retarder); (b) adds the acid component of the magnesium phosp...

Abstract

The invention discloses a two-stage stirring process of a magnesium phosphate cement-based material. The two-stage stirring process comprises the following working procedures: A, mixing water, a composite retarder and the acid ingredient of the magnesium phosphate cement-based material together, and carrying out first-stage stirring to obtain a first-stage mixture; B, mixing the first-stage mixture obtained in the working procedure A with the alkali ingredient and blend of the magnesium phosphate cement-based material together, and carrying out second-stage stirring. The two-stage stirring process has the advantages that the composite retarder and the acid ingredient of magnesium phosphate cement can be sufficiently dissolved and dispersed, so as to promote the acid-alkali reaction course, the reaction degree and strength development uniformity of the magnesium phosphate cement-based material; moreover, a cementing material can be soaked and bonded with an aggregate and a fiber interface sufficiently, and air bubbles of the final mixture can be reduced.

Description

technical field [0001] The invention relates to a mixing process of magnesium phosphate cement-based materials for construction, in particular to a two-stage mixing process of magnesium phosphate cement-based materials, and belongs to the technical field of civil engineering materials processing. Background technique [0002] Magnesium phosphate cement (MPC) is a new type of cementitious material with early strength and fast hardening. It has the advantages of fast setting at low temperature, high bond strength with concrete structure, dry shrinkage, strong adhesion, good wear resistance and frost resistance. , has a good application prospect. Magnesium phosphate cement-based materials are based on the reaction of acid-base components to form strength. Compared with Portland cement, the alkali components (dead-burned magnesium oxide powder) and acid components (phosphate) in the cementitious material are affected by moisture. The reaction should not be mixed for long-term s...
