    Abstract: Described are admixture composition and method for integrally waterproofing cementitious compositions, such as concrete and mortar, wherein an organosilicon compound (e.g., silane) is mixed with animal oil, vegetable oil, or mixture thereof, and defoaming agent. The organosilicon/oil mixtures of the present invention enhances the water repellent efficacy of the organosilicon, even as it displays inherently greater product stability, as compared to emulsion-based (and thus substantial free-water containing) admixture formulations of the prior art. Cementitious materials made in accordance with the present invention demonstrate excellent air consistency and air neutrality.

    Abstract: The present invention relates to very high workable yet controllable concrete mix design, admixture composition, and process for placing concrete. The mix design relates to particular aggregate/cement ratios and types which are characteristic of ready mix concrete (RMC), which provide high fluidity reminiscent of self-consolidating concrete (SCC), and which provides advantages over both RMC and SCC in terms of ease and speed in placement and finishability at the construction site placement zone, regardless of 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 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 to be placed in a controlled, efficient manner.

    Abstract translation: 本发明涉及非常高的可加工但可控的混凝土拌合物设计，外加剂组合物以及用于放置混凝土的方法。 混合料设计涉及特定的骨料/水泥比率和类型，它们是预拌混凝土（RMC）的特征，其提供高流动性使人联想到自密实混凝土（SCC），并且在轻松方面比RMC和SCC具有优势 并且无论是在水平模板（例如，用于板坯，地板）还是垂直模板（例如用于砌块，墙壁，立柱等）中，而不失去控制，在施工现场布置区域的布置和完成速度 即使加入少量的水以促进混凝土表面的整理，也不会产生高偏析风险。 能够实现这种独特设计的本发明混合物组合涉及两种不同的聚羧酸酯梳形聚合物与两种特定的粘度调节剂的组合，并且这种组合提供了高度可操作的混凝土，从而以受控，有效的方式放置。
