Abstract
The invention discloses a soundless cracking agent adaptive to various temperatures and a method for preparing the same. The soundless cracking agent comprises a calcium oxide, a portland cement, a water reducing agent, a phase-change material and a excitant, wherein the phase change temperature of the phase-change material is 70-100 DEG C except 100 DEG C. Compared with the prior technology, thetemperature applicable range of the inventive soundless cracking agent is -5-30 DEC C and the coagulation time and expansion pressure thereof conform to the standard of the building material industryin China about ''soundless crashing agent''.
Description
Phase change type silent breaker suitable for various temperatures and preparation method thereof technical field The invention relates to the technical field of breaking agents, in particular to a phase-change silent breaking agent suitable for various temperatures and a preparation method thereof. Background technique The Cement Science Research Institute of China Building Materials Research Institute began to study the silent breaker in 1981, and passed the ministerial technical appraisal in 1983. In the building materials industry standard of the People's Republic of China "Silent Crusher" (standard number JC506-92), "Silent Crusher" is defined as: any inorganic compound mainly calcined at high temperature, mixed with an appropriate amount of admixture and ground together The non-explosive crushing powder material with high expansion performance is called the silent crushing agent, which mainly uses calcium oxide (f-CaO) to be calcined at high temperature and then hydr...
