preparation example Construction
[0030] The preparation method of high flexure-resistant road concrete material of the present invention comprises the steps:
[0031] 1) Carry out the compatibility test of the pre-prepared concrete admixture with the slurry fluidity method, and confirm that the slurry has good initial fluidity and small fluidity loss over time, and has no hardening and no bleeding;
[0032] 2) Add the weighed stone, sand, cementitious material, and fiber into the forced mixer in turn, and dry stir for 1 to 2 minutes to fully disperse the material (fiber);
[0033] 3) Add one-half of the total mixing water and admixture (mix water and admixture first) into the mixer, and stir for 1 minute to make the cementitious material wrap the sandstone aggregate and fiber;
[0034] 4) Add the remaining water and admixture, mix the materials evenly, pour them out of the mixer, and vibrate properly for casting.
