## 1 Introduction
The raw materials used in CLSM and general concrete are not significantly different. They are also composed of coarse aggregate, fine aggregate, water, cement, and concrete. The coarse aggregate of CLSM is about 200-400 kg/m\({}^{3}\). The amount of inter- and fine-shaped aggregates is between 1280 and 1480 kg/m\({}^{3}\), which is between 700-1100 kg/m\({}^{3}\) of general concrete coarse aggregate and 700-1000 kg/m\({}^{3}\) of fine aggregate [11; 12; 13]. According to the American Concrete Association (ACI) definition, all flowable backfill, low-shrinkage controllable low-strength backfill, flowable slurry, plastic clay cementitious material, and K-Krete can be generalized CLSM [11]. Based on the early strength, many studies have been conducted to predict and analyze the compressive strength of concrete or cement mortar at 28 days or other days [14; 15; 16; 17; 18]. The results of the study show that, if some aggregate substitutes (including fly ash, slag, and waste glass) are used, the compressive strength will increase with the increase in curing time, but this increase will become stable. Previous researchers used the math function to calculate the relationship between the surface resistivity of concrete and curing age and proposed a math relationship between the compressive strength and resistivity [19; 20; 21; 22]. However, few people have proposed a prediction model for the compressive strength and surface resistance of CLSM containing desulfurization slag. This study shows that when the desulfurization slag replacement content is applied to CLSMs, it will influence the compressive strength and resistivity and, also, establish a good prediction model, which will serve as a reference for subsequent research and engineering applications. Additionally, this study attempts to establish the prediction results of the compressive strength and surface resistivity of CLSMs using the relevant mathematical functions. When the prediction mode is established, to provide a reference design, reduce the mixing workforce, test the cost of materials, and save time, the results of the preliminary test can also be applied to evaluate the material strength and durability in the later stages. [PERSON] et al. [15; 23] have studied the effects of compressive strength, flexural strength, ultrasonic wave velocity, waste glass content, water-binder ratio, and curing age for a series of matching test results of self-filling waste liquid crystal glass concrete. The relationship between the factors and, according to the test results, the hyperbolic function, the exponential function, and the power function, are used to perform a nonlinear multivariate regression analysis, and the prediction can be reasonably evaluated. Therefore, this paper will analyze and verify the compressive strength and resistivity of controlled low-strength desulfurization slag materials according to the prediction model proposed by the author and others for waste liquid crystal glass concrete to evaluate whether the analysis mode is applicable for further research. It is intended to be suitable for the predictive model of controlled low-strength desulfurization slag materials. Similarly, the starting point of waste reprocessing and sustainable development, including the addition of desulfurized slag and other raw material alternatives of CLSMs, constitutes a good research topic of the study.
