Study On Physical Mechanical Properties Andapplication Of Ready-Mixed Mortar

Ready-mixed mortar can’t effectively control product quality,no professional laboratory,mortar formula is not scientific;Lack of mortar production process monitoring,ensuring product quality,the quality of raw material and mortar work ability is poor,bad construction;Unable to mechanical construction and the manual construction,leading to low efficiency of construction,construction is a big obstacle to modernization;Mortar quality is not stable,lead to empty drum,chromatic aberration,cracking and other phenomena can be seen everywhere.Outdoor stacking materials,covers an area of big,contrast of dust control,can’t really do civilization construction;The mixing quantity is difficult to control,waste is big,is not conducive to build a conservation-minded society.Ready-mixed mortar products quality control professional laboratory to provide accurate mortar formula,and the mortar production process monitoring,raw materials used in the production and quality products are guaranteed;Factory production to ensure the quality of the mortar consistent;Professional special mortar admixture,full compliance with site construction needs.Mortar construction good work ability,easy to construction;Mortar quality stable and reliable,can basically eliminate common empty drum,off color,such as cracking mortar "disease”;Suitable for mechanized construction can increase efficiency of the construction.Sealed transportation,sealed storage,put an end to "run leakage risk",accurate mixing use,how much we use stirring,no waste;No material yard,cover an area of an area small,truly civilized construction.Thesis research object of ready-mixed mortar,this paper introduces the countermeasures and the existing problems of ready-mixed mortar,ready-mixed mortar material composition,characteristics and material properties,physical and mechanical properties of ready-mixed mortar,and the characteristics of production and construction technology of ready-mixed mortar.Through to the ready-mixed mortar and traditional mortar for physical and mechanical properties of cement mortar,production verification test,the characteristic of construction and so on the test results show that the adjustment of dosage of admixture,fully able to meet the requirements of ready-mixed mortar of setting time;With the right water thickening material can obviously improve the mortar of caking property,make mortar bond strength meet the specified requirements,and thus to effectively improve avoid engineering that exist in the empty drum,the phenomenon such as blast walls;Ready-mixed mortar water thickening material preparation of slurry under the condition of the same consistency,water retention is better than traditional mortar.Analyzes the factors influencing the performances of mortar;for its production and quality control are also put forward some Suggestions and measures.
