SUPER PLASTICIZER POLYMER SYNTHESIS

Abstract

In this study, it is aimed to synthesize more environmentally friendly and low-cost biopolymer based super plasticizers (SP) by using biopolymers (starch, chitosan polysaccharide, floral oils, etc.), acrylic acid, maleic anhydride, sodium vinyl sulphonate and various corn starches and various catalysts. These raw materials have been examined in terms of their water holding capacity, viscosity, bond structures and renewability. For the structure determination of the synthesized products, FT-IR, fluidity and compressive strength tests are performed. Because it is aimed also to meet the local consumption of cement materials additives in Turkey. In this process, it is to protect our environment by making it bio-based as much as we can, away from today's chemicals and petroleum derivatives. Three different types of polymer are synthesized: flower oil, bowine gelatine and mpeg5000. The ratio of sand:cement:water in the cement mixture used in the study is 2:1:0.45. Synthesized SP polymers were added to the cement mixture at a rate of 0.75%. In the experiments by connecting a plurality of parameters when selecting the appropriate optimal values according to the appropriate product and polymerizing bond products it was synthesized. FTIR results match the peaks in each raw material. So detailed generalization of the bond structure is appropriate. It can be said that bio raw material synthesis is encouraging in the future, and it can be found that form the compressive strength test, the flower oil being more resistant. As a result of this study, three types of polymeric additives were successfully synthesized and analyzed and performance tests were completed.
