Control of organic water-reducing admixtures in binding materials and organo-mineral additives

The report deals with the development of optimum parameters for the photocolorimetric method of monitoring the weight ratio of organic water-reducing admixtures based on polymethylene-naphthalene sulfonates, lignosulfonates, including when they are jointly present in construction materials (cement, concrete, dry mixes, etc.) and organo-mineral additives.
