[0028] A non-pyrophoric fine stone concrete and its manufacturing technology. The components and mass parts of the non-pyretic fine stone concrete are as follows: 350 parts of cement, 750 parts of non-pyretic fine aggregate, 950 parts of non-pyretic coarse aggregate, and expansion agent 30 parts, 150 parts of admixture, 13 parts of compound admixture. Wherein the cement is 42.5 grade ordinary cement, and the non-fire fine aggregate is limestone or dolomite machine-made sand (fineness modulus = 2.0-2.8, the non-fire performance of the raw material is qualified after inspection, and the iron is removed by the iron remover. quality debris), the non-pyrophoric coarse aggregate is limestone or dolomite machine-made stones (5-16mm continuous gradation, non-pyrophoric performance passed the inspection), the expansion agent is calcium sulfoaluminate type expansion agent, The admixture is obtained by compounding silica fume and fly ash at a ratio of 1:6, and the additive is obtained by...

Abstract

The invention discloses explosion-proof pea gravel concrete and a production method thereof. The explosion-proof pea gravel concrete is produced from the following components in parts by mass: 300-600 parts of cement, 400-800 parts of explosion-proof fine aggregate, 500-1000 parts of explosion-proof coarse aggregate, 20-40 parts of an expansion agent, 100-180 parts of an admixture, and 10-20 parts of a compounding admixture. Compared with similar products and the prior art, the explosion-proof pea gravel concrete has the advantages that raw materials are explosion-proof, the performance control is scientific and rigorous, the concrete is not segregative, self compaction can be realized, and a concrete surface does not cause sand streak and is free from cracking. The explosion-proof performance of the concrete is safe and reliable, and the quality is uniform and level. When being free from doping with the coarse aggregate, the explosion-proof pea gravel concrete is explosion-proof mortar.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a non-fire fine stone concrete and a preparation method thereof. Background technique [0002] Ordinary non-pyrophoric concrete has the following problems: 1. Temporary procurement of raw materials, the quality is uneven, especially the non-pyrophoric performance of raw materials is not easy to control; 2. On-site proportioning and mixing are prone to segregation and poor quality stability; 4. The water retention is poor, and the concrete surface is prone to drying shrinkage and temperature stress cracking. Contents of the invention [0003] In order to solve the problem of uniform quality of non-pyrophoric concrete prepared on site, the problem of non-pyrophoric performance control of raw materials, and the common quality problems of such concrete such as segregation, sanding, and cracking, the invention provides a non-pyrophoric fine stone concrete and a preparation ...
