Hormigoizko Gehigarri Arinak | Hormigoi zelularentzako errendimendu handiko apar-agenteak
Superplastificante bat hormigoiaren langarritasuna areagotzen duen hormigoiaren gehigarri bat da, ur edukia murrizten duen bitartean. Horrek langileei nahastea errazten die, hormigoia bota eta amaitu, baita amaitutako produktuan juntura hotzak izateko arriskua murrizten du. Horrez gain, gehitutako gehigarriak hormigoiaren erresistentzia hobetuko du.
Superplastificanteak uretan disolbagarriak diren polimero-molekulaz osatuta daude. Hormigoiarekin nahasten denean, molekula hauek zementu partikulen gainazalean lotzen dira. Horrek lotura ionikoa sortzen du molekularen eta zementu-aleen artean. Eragozpen esterikoa ere murrizten du, hau da, molekula barneko edo molekula arteko elkarrekintzak eragindako muga.
Hormigoizko superplastizatzaileen merkatu globala azkar hazten ari da. This is mainly due to the high demand for ready-mix concrete (RMC) in construction projects worldwide. The demand for RMC is expected to increase further with the development of various infrastructure projects in the near future.
In order to meet the growing demand for RMC, companies are focusing on manufacturing superior quality concrete with the help of advanced technologies. Superplasticizers are among the essential ingredients used in RMC. These chemicals are responsible for transforming low-slump and stiff concrete into a flowable, smooth material. They also assist in lowering the w/c ratio and help reduce shrinkage cracking tendencies of the hardened concrete.
