CH concrete water-reducing agent is a new type of water-reducing agent that is modified by using paper mill grass pulp (C) black liquor (H). This article is divided into (1) the chemical composition and physical properties of the CH agent; (2) the synthesis process of the CH agent; (3) the selection of the best content of the CH agent in the concrete; (4) the main physical and mechanical properties of the CH agent on the concrete. (5) The relationship between the reinforcing effect of CH agent on concrete and the saving of cement; (6) The effect of CH agent on the strength of concrete at different ambient temperatures; (7) The effect of CH agent on the setting time of concrete; (8) CH The impact of the agent on the impermeability of concrete; (ix) The use of CH agent and its application effect in the construction of twelve chapters, a more comprehensive introduction to the development, production and use of CH agent.
