No spark fine stone concrete mixture ratio

Not angry no spark fine stone concrete mix proportioning of fine stone concrete table 1 misfire test block with classification of fine stone concrete aggregate composition and the experimental results of category A B C D aggregate marble powder, 32. 5 r cement marble stone, 32. 5 r cement, sand, marble powder, marble stone, 32. 5 r cement marble powder, ordinary gravel, 32. 5 r cement test whether purpose ignition, can meet the strength requirements block size is 150 * 150 * 150 ( cm） If applicant is no angry compressive strength is 10. 5MPa 18. 2MPa 17. 5MPa 19. 0 mpa test: Li Gong technical guidance calls; 13213116342 don't get angry about the misfire of fine stone concrete testing methods: in a dark room or at night, with 15 cm emery wheel on a handheld grinder, equivalent to about iron artifacts from 3 m high free fall impact the linear velocity of the ground, to block edges for cutting or grinding, if a spark is unqualified, do not produce qualified! Compressive strength test, and the common concrete block compression test. Through the analysis of experimental comparison, the following conclusions: 1. No spark fine stone concrete can't sand used as fine aggregate, and can only use marble stone ground to a powder or white clouds for fine aggregate. 2. Coarse aggregate can only be used with marble, dolomite, cannot use normal granite rock! To meet the requirements of misfire and meet the requirements of the compressive strength, also need to add some add the seam an agent!
