Use of sodium carbonate as fired fly ash brick blank plasticizer

Abstract

The invention discloses a use of sodium carbonate as fired fly ash brick blank plasticizer and belongs to field of building materials. Experiments find that sodium carbonate can be used as fired fly ash brick blank plasticizer for preparing fired fly ash brick. Mixture of sodium carbonate and fly ash is blended by weight ratio of 3.5-4.5:96.5-95.5 and plasticizing effect is good. Sodium carbonate is used as fired fly ash brick blank plasticizer for preparing fired fly ash brick with low cost, good plasticizing effect and no influence on molding of admixture.

Description

technical field [0001] The invention relates to a new application of sodium carbonate, in particular to the application of sodium carbonate as a plasticizer for sintered fly ash brick blanks, and belongs to the field of building materials. Background technique [0002] From June 1, 2000, some coastal cities and cities with insufficient land resources have banned the use of clay bricks, and restricted the production and use of other clay products according to conditions. Cities such as Beijing and Shanghai banned the use of ordinary clay bricks in January 2000. At present, the country has identified 170 large and medium-sized cities to restrict the ban on clay bricks. [0003] "2009-2012 China's New Building Materials Industry Investment Analysis and Prospect Forecast Report" pointed out: In recent years, China's wall material innovation and promotion of energy-saving buildings have made positive progress. In 2006, the national output of new wall materials reached 385 billio...
