| Abstract: | A new kind of gypsum-based self-leveling mortar with fine fluidity and high strength property has been developed with semi-hydrated gypsum by mixing quartz sand,water reducing agent,retarder,water retaining agent,antifoaming agent and EVA in it.Tests showed the main performances of this mortar reached or exceeded the requirements of Standard JC/T 1023-2007,for instance,fluidity loss was less than 3 mm;flexural strength and compressive strength respectively reached to 32.30 MPa and 10.4 MPa,cohesional streng... |
