NOVELTY - A limestone accelerator comprises 20-24 pts. wt. bauxite , 7-11 pts. limestone , 12-16 pts. sodium carbonate , 4-8 pts. non-ionic linear high molecular polymer , 6-10 pts. aluminum oxide , 5-9 pts. silicon dioxide , 2-6 pts. additive , 2-6 pts. latex powder , 1-5 pts. composite flow agent , 3-7 pts. silicon ash , 4-8 pts. calcium oxide , 6-10 pts. polyamide wax , 9-13 pts. microcrystalline cellulose , 4-7 pts. air entraining agent , 4-7 pts. cellulose ether , 1-5 pts. ion group , 6-10 pts. graphene oxide , 5-9 pts. carbon nano tube, and water. USE - Limestone accelerating agent. ADVANTAGE - The limestone accelerator ensures the strength of the concrete, ensures the post strength of the concrete, reduces the slump loss, can effectively improve the size of the coarse particle and accelerating agent transition region crystal in the concrete, increases the compactness of the transition region crystal, reduces the porosity, reduces the micro-crack number of the transition area, improves the whole strength of the concrete, and also can make the coarse particles and accelerating agent mixing more uniformly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the limestone accelerator.
