Ardealite-based super-retarding concrete and preparation method thereof
The invention discloses ardealite-based super-retarding concrete which comprises a basic raw material, a water reducing agent, a super-retarding agent and an additive, the basic raw material comprises 100-180 parts of mineral powder; 20 to 80 parts of fly ash; 5 to 35 parts of cement; 900 to 1200 parts of sand; 800 to 1000 parts of stone; the super-retarding agent is prepared from 120 to 180 parts of modified ardealite; 0.5 to 1.5 parts of white sugar; 0.7 to 2 parts of sodium gluconate; and 0.005 to 0.015 part of cellulose ether. The ardealite is used as a main cementing material to form an ardealite-based super-retarding concrete system, and soluble phosphate, white sugar and sodium gluconate in the ardealite are compounded to jointly achieve a super-retarding effect. The ardealite-based super-retarding concrete is low in cost, utilizes a large amount of ardealite, and is green and environment-friendly; the ardealite can be normally used after simple treatment, and the steps are simple.
本发明公开了一种磷石膏基超缓凝混凝土，包括基础原料、减水剂、超缓凝剂和外加剂；基础原料包括矿粉100份～180份；粉煤灰20份～80份；水泥5份～35份；砂子900份～1200份；石子800份～1000份；超缓凝剂包括改性磷石膏120份～180份；白糖0.5份～1.5份；葡萄糖酸钠0.7份～2份；纤维素醚0.005份～0.015份。本发明的磷石膏作为主要的胶凝材料，构成磷石膏基超缓凝混凝土体系，磷石膏中的可溶性磷酸盐、白糖和葡萄糖酸钠复配共同起到超缓凝的作用。本发明的磷石膏基超缓凝混凝土成本低廉，且利用了大量磷石膏，绿色环保；磷石膏经简单处理即可正常使用，步骤简单。
