    Mar 23 2018 · Additionally high temperature issues are of concern especially in mass concrete pours where the core temperature can be very high due to the mass effect while the surface temperature is lower. This causes a temperature gradient between the surface and the core if this differential in temperature is too large it will cause thermal cracking.

  • Effect of clinker grinding aids on flow of cement-based

    Sep 01 2014 · Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This paper seeks to assess the effect of such additions on variations in flow of cement pastes including static yield stress (τ 0) and viscosity (η).Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness.
