This document provides information on ADDMIX@ 922 BRX, a ready-to-use liquid admixture designed to produce rheoplastic qualities in concrete. Some key points: - It improves strength, lowers permeability, and improves durability, pumping, and workability. - Testing shows it considerably improves compressive strength when dosed at 1L per 100kg of cement. - It is normally dosed at 0.7-1.2L per 100kg of cement but dosages may vary depending on conditions.
