A novel artificial intelligence (AI) application was proposed in the current study to predict CTF’s compressive strength (CS). The database contained six input parameters: age of curing for specimens (AS), cement–sand ratio (C/S), maintenance temperature (T), additives (EA), additive type (AT), concentration (AC), and one output parameter: CS. Then, adaptive boosting (AdaBoost) applied existing AI soft computing techniques, using AdaBoost, random forest (RF), SVM, ANN. Data were arbitrarily separated into training (70%) test (30%) sets. Results confirm that AdaBoost RF have best prediction accuracy, with a correlation coefficient (R2) 0.957 between these sets AdaBoost. Using Python 3.9 (64-bit), IDLE (Python 64-bit), PyQt5 achieve machine learning model computation software function interface development, this can quickly property CTF specimens, which saves time costs efficiently backfill researchers developing new eco-efficient components.

This paper proposes a new type of gangue filling body (GFB) to address the issues low stability, strength, poor shrinkage performance, and inadequate seepage resistance paste materials in overburdened mining conditions, as well challenge fully utilizing solid waste gangue. The coal (CG), U-expanding agent (UEA), amount water added were kept constant, mass ratio various components was adjusted design. standard for assessed using slump tests, uniaxial compression penetration tests. A further microscopic analysis pastes with an optimal performance conducted SEM. support pressure overburden migration patterns GFBs evaluated Flac3D. results indicate that GFB 4 performed best, highlighting significant role Portland cement (OPC). 3 demonstrated second-best suggesting higher early strength should be chosen fill hollow zones effective outcome. study introduced material confirmed rock transport law this under conditions Flac3D, offering insights engineering field.

As a new type of backfill material, Self-compacting solidified soil (SCSS) takes the abandoned slurry cast-in-place piles after dewatering and reduction as main raw which brings problem coordinating working performance with mechanical property under condition high mobility. In this paper, hydroxypropyl methyl cellulose (HPMC) metakaolin were introduced additives to solve problem. First, workability properties SCSS regulated optimized by means water seepage rate test, flowability unconfined compressive strength test. Second, study also used X-ray diffraction (XRD) scanning electron microscopy (SEM) investigate effects HPMC on physical phase microstructure SCSS. way, results showed that there was significant impact SCSS, is, when dosage reached 0.3%, reduced less than 1%, at 7 days its peak. At same time, weakened growth in age period 14 days. However, addition promoted strength. XRD analysis had no phases. And, from SEM results, it can be seen although water-retaining effect makes hydration cement more exhaustive, ettringite (AFt) observed microstructure. addition, generate hydrated calcium silicate (C-S-H) due strong surface energy possessed metakaolin. result above factors, filled voids between particles improved interface structure particles, thus enhanced
