The mix design relates to particular aggregate/cement ratios and types which are characteristic of ready 'IlL ' mix concrete (RMC), which provide high fluidity reminiscent of self-consolidating concrete (SCC), and which provides advantages 01 over ei both RMC and SCC in terms of ease and speed in placement and fmishability at the construction site placement zone, regardless of in whether into a horizontal formwork (e.g., for slabs, floors) or into vertical formwork (e.g., for blocks, walls, columns, etc.), without loss - of control and without generating high risks of segregation even when small amounts of water are added at the size to facilitate finishing IN of the concrete surface. An inventive admixture combination which enables this unique design involves two different polycarboxylate ---.. © comb polymers in combination with two specific viscosity modifying agents, and this combination provides highly workable concrete c)1: 1-1 to be placed in a controlled, efficient manner. 0 ei O [Continued on next page] WO 2018/071529 Al MIDEDIMOMMIDIROIENHER1111111111111111101111111111111111111 EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, SK, SM, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
