What is the general solid content of additives? How to detect

The appearance of additives can be divided into aqueous and powder forms. The solid content of water agents is generally20%，40%(also known as mother liquor),60%The solid content of powder is generally98%According to the water reducing and enhancing abilities of water reducing agents, they are divided into ordinary water reducing agents (also known as plasticizers) with a water reduction rate of not less than8%Represented by lignosulfonates[2]）Water reducing agent (also known as superplasticizer), with a water reduction rate of not less than14%Including naphthalene series, melamine series, aminosulfonate series, aliphatic series, etc[2]）And high-performance water reducing agent (with a water reduction rate not less than25%Represented by polycarboxylate superplasticizers[2]）It is further divided into early strength type, standard type, and slow setting type. powder≥94%, liquid concentration0-40%

Admixtures are concrete admixtures that can reduce the amount of water used in mixing while maintaining the same slump of concrete. Most of them belong to anionic surfactants, including lignosulfonates, naphthalene sulfonate formaldehyde polymers, etc. After adding concrete mixture, it has a dispersing effect on cement particles, which can improve its workability, reduce unit water consumption, increase concrete strength and improve durability; Or reduce the unit cement consumption to save cement.

How to detect the solid content of additives:

In the field of solid content detection, the contradiction between measurement accuracy and measurement speed has not been resolved; In response to this situation, Shenzhen Fenxi Instrument Manufacturing Co., Ltd. provides an instrument with a drying method structure for rapid determination of solid content values.CSY-G2Additive solid content detectorAdopt GermanyHBMWeighing system to ensure accurate weighing; Circular quartz tungsten halide infrared heating source for rapid drying of samples; Compared with the oven heating method, the annular quartz tungsten halide infrared heating can uniformly and quickly dry the sample at high temperatures, and the surface of the sample is not easily damaged. Its detection results have good consistency with the national standard oven method,It has substitutability and detection efficiency far higher than the oven method, with intelligent operation,Generally, the sample can be measured in just a few minutes.CSY-G2Solid content detector receives * protection (number)201420090168.1）It is a new type of rapid detection instrument.
