A rachadura \u00e9 um dos problemas mais comuns e caros na constru\u00e7\u00e3o de concreto. Ela afeta n\u00e3o apenas a apar\u00eancia, mas tamb\u00e9m a durabilidade, o desempenho da impermeabiliza\u00e7\u00e3o e a resist\u00eancia a longo prazo das estruturas de concreto. Felizmente, com os aditivos de concreto certos para evitar rachaduras, \u00e9 poss\u00edvel reduzir significativamente a forma\u00e7\u00e3o de rachaduras e melhorar a qualidade geral da mistura.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A r\u00e1pida perda de \u00e1gua pode causar rachaduras por retra\u00e7\u00e3o pl\u00e1stica no concreto antes que ele endure\u00e7a. Ao reter a umidade na mistura por um per\u00edodo mais longo, o HPMC permite que o cimento endure\u00e7a de forma mais uniforme e reduz o risco de rachaduras na superf\u00edcie.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
