Embodiment 1-5
[0040] A high-performance ready-mixed concrete prepared from concrete mixture, which includes the following raw materials: Portland cement, fine aggregate, coarse aggregate, mineral admixture, water, polycarboxylate high-efficiency reducer Aqueous agent, triterpene saponin, fatty alcohol polyoxyethylene ether sodium sulfate.
[0041] Among them, the fine aggregate is medium sand.
[0042] Coarse aggregate is one or more mixtures of natural stone and crushed gravel with an average particle size of 12mm.
[0043] The mineral admixture is fly ash and slag powder, and the weight ratio of fly ash and slag powder is 1: (0.9-1.1).
[0044] Refer to Table 2 for the specific selection and dosage of the above various raw materials.
[0045] The preparation method of high-performance ready-mixed concrete comprises the following steps:
[0046] Step 1): Heating triterpene saponins, fatty alcohol polyoxyethylene ether sodium sulfate, and water at a specified temperature, and stirring at...
Embodiment 6
[0054] A high-performance ready-mixed concrete, the difference from Example 5 is that the polycarboxylate superplasticizer is CC-AI polycarboxylate superplasticizer.
Embodiment 7
[0056] A kind of high-performance ready-mixed concrete, and the difference with embodiment 5 is that, in step 3), also put into with sulfamate superplasticizer, sulfamate superplasticizer and polycarboxylic acid superplasticizer The weight ratio of the agent is 0.5:1, that is, the input amount of the sulfamate superplasticizer is 0.95kg.
