[0022] As shown in the figure, a method for preparing plastic concrete with a high water-binder ratio according to the present invention comprises the following steps:
[0023] Step 1: Mix water and bentonite, and stir evenly, then seal and place in a constant temperature box at a temperature of 20°C for 24 hours to make it fully expanded to obtain bentonite slurry, which is ready for use;
[0024] Wherein, the weight ratio of water and bentonite in the bentonite slurry is 22:4, usually, the weight part of water is 22, and the weight part of bentonite is 3-4;
[0025] The water used is deionized water with conductivity less than 0.1μs / cm;
[0026] The bentonite is at least one of calcium-based bentonite and sodium-based bentonite, and the particle size is 0.075-0.5mm;
[0027] Step 2: Dry mix cement, slag powder, steel fiber, and sand evenly to obtain a mixed dry material for use;
[0028] Wherein, the weight ratio of cement, slag powder, steel fiber and sand in the mixed dr...
Embodiment 1
[0034] Embodiment 1: The present embodiment provides a kind of high water-binder ratio plastic concrete, comprises: the water of 22 parts by weight, the Inner Mongolia bentonite of 4 parts by weight, the cement of 2 parts by weight, the slag powder of 7 parts by weight, the slag powder of 1 part by weight Steel fiber, 64 parts by weight of sand, i.e. plastic concrete with a water-binder ratio of 1.7;
[0035] Specifically, 4 parts by weight of Inner Mongolia bentonite was poured into 22 parts by weight of water, and stirred for 120s, then sealed and placed in a thermostat at a temperature of 20°C for 24 hours, and the conductivity of the water used was deionized water of 0.098 μs / cm , Inner Mongolia bentonite is calcium-based bentonite with a particle size of 0.1 mm; after Inner Mongolia bentonite is expanded for 24 hours, mix 2 parts by weight of cement, 7 parts by weight of slag powder, 1 part by weight of steel fiber and 64 parts by weight of sand and stir for 60 seconds , ...
