Embodiment Construction
[0062] The present invention will be further described below in conjunction with specific embodiments.
[0063] A durable sulfur concrete modified by coal tar, the proportions of each component are as follows:
[0064] Industrial sulfur particles 1080kg, sulfur content ≥ 99.95%, moisture ≤ 2.0%;
[0065] Granular crushed stone 600kg, particle size is 4.75 ~ 20mm;
[0066] 73kg of fly ash is the waste generated by coal combustion in the Ordos area, and the sieve allowance of 45μm square-hole sieve is not more than 12%;
[0067] The granulated blast furnace slag is 41kg, which is the original blast furnace slag of Xuangang, and the apparent density is 2.52g / cm 3 , the fineness modulus is 2.60;
[0068] The quartz sand is 342kg, which is high-quality quartz sand produced in Tongliao, Inner Mongolia, with a particle size of 0.075-0.125mm;
[0069] The waste ceramic fine aggregate is 29kg, which is the fine aggregate obtained by crushing, processing and sieving the waste cerami...
