Embodiment Construction

[0014] The present invention will be further described below.

[0015] A method for producing dry-mixed mortar, comprising the following steps;

[0016] Step 1: remove the reinforcing steel material in the construction waste, and then crush it and sieve it. After sieving, the material on the sieve is aggregate, and the material under the sieve is construction waste sand; the particle size of the aggregate is ≤55mm;

[0017] Step 2: Proportion the mixture according to the following parts by weight: 3 to 5 parts of cement, 13 to 18 parts of natural sand, 1 to 2 parts of fly ash, 42 to 55 parts of construction waste sand, and 20 to 30 parts of aggregate ;

[0018] Step 3: put the mixture and admixture into the dry-mixed mortar mixer, and fully stir it through the dry-mixed mortar mixer to make it evenly mixed to obtain dry-mixed mortar powder.

[0019] The invention adopts construction wastes as raw materials for dry-mixed mortar, effectively utilizes and reduces construction w...

Abstract

The invention provides a production method of dry-mixed mortar. The production method comprises the following steps: step 1: removing steel bar materials in building waste materials; then crushing thebuilding waste materials and sieving, wherein an oversize material is aggregate and an undersize material is building waste sand after sieving, and the grain diameter of the aggregate is less than orequal to 55mm; step 2: proportioning a mixture in parts by weight: 3 to 5 parts of cement, 13 to 18 parts of natural sand, 1 to 2 parts of fly ash, 42 to 55 parts of the building waste sand and 20 to30 parts of the aggregate; step 3: adding the mixture and an additive into a dry-mixed mortar mixing machine, and sufficiently stirring by the dry-mixed mortar mixing machine and uniformly mixing toobtain dry-mixed mortar powder. By adopting the method provided by the invention, the dry-mixed mortar can be produced by sufficiently utilizing the building waste materials and the environment pressure caused by building wastes can be effectively alleviated.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production method of dry-mixed mortar. Background technique [0002] With the steady development of the national economy and the advancement of urbanization, the construction industry has developed rapidly, and the demand for various mortars in the construction process has also increased sharply. In some building construction processes, a large amount of construction waste will be generated, most of which are directly discarded, and their utilization rate is extremely low. Using construction waste as a raw material for dry-mixed mortar can not only alleviate the environmental pressure brought by construction waste, but also solve the problem of insufficient raw materials for dry-mixed mortar. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a dry-mixed mortar production method, which can mak...
