Problems solved by technology

[0002] The commercial and residential buildings in my country in the 1970s and 1980s were generally poor in construction quality due to the economic and technical conditions of our country at that time. At present, they are all facing demolition and reconstruction. The construction waste generated by demolition (mainly wall materials: clay sintered bricks, concrete and components), how to deal with it has become a difficult problem in the construction industry. Generally, fish ponds and farmland in the urban-rural fringe are used to landfill, causing serious environmental pollution and reduction of cultivated land

Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiment:

[0022] A production process for preparing ready-mixed dry-mixed mortar from recycled aggregates, comprising the following steps:

[0023] The first step is to classify the construction waste, and take the waste concrete and waste sintered bricks and store them separately;

[0024] The second step is to crush waste concrete and waste sintered bricks to form waste concrete recycled aggregates and waste sintered bricks recycled aggregates; specifically, the crushing includes the early crushing of the crocodile crusher and the crushing of the hammer mill. Post-stage crushing, so as to obtain recycled aggregates with a diameter less than or equal to 2.5mm, and perform secondary crushing on the recycled aggregates larger than 2.5mm to form recycled aggregates with a diameter of 2.5mm or less, and after the crushing is completed, Detect recycled aggregates with a diameter less tha...

Abstract

The invention discloses a production technology for preparing premixed dry-mixed mortar from recycled aggregate. The production technology comprises the following steps that firstly, building waste is classified; secondly, waste concrete and waste sintered bricks are smashed to form the recycled aggregate; thirdly, the recycled aggregate is screened and classified according to the diameter specification and stored; fourthly, cement is taken and put into a cement metering bin for use, and additives are taken and put into corresponding additive metering bins, wherein the additives comprise a water-retaining agent, a water reducing agent, an air entraining agent, a thixotropic lubricating agent and an infiltration dispersing agent; fifthly, the materials in all the metering bins in the third step and the fourth step are metered according to proportions, discharged out of the bins and mixed, and the premixed dry-mixed mortar is formed. The production technology for preparing the premixed dry-mixed mortar from the recycled aggregate can reduce environment pollution while the high-performance premixed dry-mixed mortar is prepared.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a production process for preparing ready-mixed dry-mixed mortar from recycled aggregates. Background technique: [0002] The commercial and residential buildings in my country in the 1970s and 1980s were generally poor in construction quality due to the economic and technical conditions of our country at that time. At present, they are all facing demolition and reconstruction. The construction waste generated by demolition (mainly wall materials: clay sintered bricks, concrete and components), how to deal with it has become a difficult problem in the construction industry. Generally, fish ponds and farmland in the urban-rural fringe are used for landfill, causing serious environmental pollution and reduction of cultivated land. Invention content: [0003] The technical problem to be solved by the present invention is to provide a production process for preparing ready-mixed dr...
