Research on two-component spray polymer slurry: balancing rheological stability and rapid solidification

Research Overview

Based on the research included in Volume 547 of Construction and Building Materials (published on November 14, 2026), authors Yuanshan She, Yuxuan Chen, and Qingliang Yu proposed a design concept for a two-component sprayed geopolymer slurry, aiming to simultaneously satisfy two usually interdependent properties during construction: long rheological stability and rapid setting. This study belongs to the field of building cementitious materials and construction formulations, involving material performance indicators such as two-component system design, slurry rheological behavior, and setting time.

Core facts and data

It should be noted that the source text only provides the title, publication information, and author information, and does not disclose specific formula composition, rheological test parameters, setting time values, or mechanical performance data. Therefore, this article does not make any inferences about the above indicators.

Significance for the construction and home decoration materials and polymer additives industry

During the pumping, pipeline transportation, and spray molding processes of the adhesive materials used in spray coating construction, it is necessary to maintain a stable rheological state within a certain time window to avoid premature thickening that may cause pipe blockage or poor atomization;

; And after being sprayed onto the base, it is hoped to solidify as soon as possible to shorten the opening time, reduce sagging and dripping. The contradiction of “long construction window and fast curing after forming” is a common formula design difficulty in building coatings, sealants, waterproof slurries, and PVC profiles and pipe materials. This study takes a two-component system as the starting point to address this contradiction, and its approach has reference value for the development of inorganic cementitious materials, repair mortar, and spray waterproof layer formulations in the fields of architecture and home decoration. From the perspective of polymer additives, the synergistic requirements for rheological control and coagulation behavior in two-component spray systems usually require the introduction of rheological modified components, dispersion and stabilization systems in the formulation, and maintaining consistent performance during storage and construction stages. For architectural coatings and waterproofing systems, weather resistance and stability are also key to long-term performance. Antioxidants and light stabilizers are commonly used to inhibit the degradation of polymer substrates under UV, heat, and oxygen conditions; The design of weather resistant and stable systems in outdoor building materials such as PVC profiles is directly related to the appearance maintenance and service life of the products. Although this study focuses on the polymer slurry itself and does not involve polymer additives, its approach to balancing rheological stability and setting speed during the construction phase can provide methodological references for the selection and system matching of additives in building material formulations.

Information to be noted

The specific two-component composition, rheological stability testing method, and setting time data of this study have not been provided in the source. In the future, attention should be paid to the formula details and performance indicators disclosed in the full text of the paper to determine its applicability to actual construction and home decoration scenarios.
