JC/T2329—2015《水泥基自流平用界面剂》标准解读

Standard interpretation of JC/T 2329—2015 "interface agent for cement-based self-leveling cement"

对JC/T 2329—2015《水泥基自流平用界面剂》标准进行解读。简述了标准编制的目的和意义,详细说明了主要技术指标的确定。将4 h表面吸水量超过0.5 ml的基层材料定义为吸水性基材,例如混凝土、水泥砂浆等;4 h表面吸水量不超过0.5 ml的基层材料定义为非吸水性基材,例如釉面砖、玻化砖等。将涂刷有界面剂的瓷砖粘贴在混凝土板上再按照JC/T 985—2005测试粘结强度,能客观反映材料的粘结性能,并且确定粘结强度指标大于1.0 MPa。同时对不挥发物含量、p H值、表干时间等技术指标也进行了确定。

This paper interpreters the JC/T 2329--2015 standard for ＂interface agent for cement-based self-leveling＂. Expounds the purpose and meaning of standards establishment, details the determination of main technical indexes,base material with 4 h surface water quantity more than 0.5 ml ＂is defined as the water imbibition backing material, such as concrete and cement mortar, base material ＂with 4 h surface water quantity not more than 0.5 ml is defined as the non-water imbibition backing material, such as glazed brick,vitrified brick,etc. The tiles painted with interface agent attached to a concrete slab and then conduct bond strength test according to the JC/＇r 985~2005,it can objectively reflect the adhesive properties of materials, and determine the bond strength indicators need to,be more than 1.0 MPa. Meanwhile non-volatile matter content,pH value,dry time technical indicators have also been identified.
