US: GCP Applied Technologies has launched two new cement additives: Opteva HE quality improvers and Tavero VM grinding aids. Opteva HE is intended to enhance early strength and is targeted at ‘challenging’ cements. Tavero VM is a grinding aid additive intended to help stabilise vertical roller mills during production by reducing water injection requirements and cement pre-hydration. It also improves cement performance by delivering higher strengths and shorter setting time.
