摘要
研究了早强组分、黏结保水组分、引气组分、减水组分等对干混砂浆性能的影响,通过改变各组分的种类和掺量,研究了对M10抹面砂浆的保水性、抗压强度、黏结强度等性能的影响,研制出一种新型干混砂浆复合外加剂,应用于实际工程中,提高了干混砂浆的和易性及强度,满足了工程抹面厚度为50 mm的要求,且易于施工。
It was studied the effect of early strength component,water retention component,air lead component and water reducing group on the performance of dry mixed mortar, by changing the type and dosage of each component, study the effects on water retention, compressive strength, bond strength and other properties of M10 mortar, developed a new type of dry mixed mortar composite admixture used in practical engineering, improve dry mortar workability and strength, meet the engineering precausions the thickness of 50mm, and easy construction.
