Enhancing strength performance while reducing cement consumption for soil stabilization is the key to improving economic benefits of engineering construction projects like retaining structures underground engineering, subgrade bases, and foundation reinforcement. This study employed metakaolin as additive realize these two aims. A series compression microstructural observation tests on cement- ...

This study aimed to explore the use of additives in soil–cement mixtures that have undergone a wetting-drying cycle. In total, two types soil were used, granitic and lateritic, which are widely used road base construction Katingan area, Central Kalimantan, Indonesia. The cement was ordinary Portland type I, while additive utilized for commercial purposes, predominantly contained CaCl2. research...

This study reports a synthetic polymer functionalized with catechol groups as dental adhesives. We hypothesize that a catechol-functionalized polymer functions as a dental adhesive for wet dentin surfaces, potentially eliminating the complications associated with saliva contamination. We prepared a random copolymer containing catechol and methoxyethyl groups in the side chains. The mechanical a...

The paper considers the issues of energy consumption and effectiveness using aluminous slag as an expansion agent compared to Portland cement. Aluminous is a difficult material grind, but its use additive in demand for building materials. following research methods were used: grinding materials, sieve analysis, electron microscopy. According results studies, it was found that effective

In this study, 10–50% of porcelain tile polishing residue (PPR) was used as an additive or partial replacement cement in concrete. The consumption kept constant by correcting the amount sand for each mixture. Concrete workability (slump) reduced up to 88.72% when PPR replaced 30%, while it only 4.10% added concrete at same levels. Compressive strength 28 days increased 92.22% with 50% additive,...

Purpose: This research was intended to evaluate Nano silica as an additive improve the sulphate resistance of cement used in geothermal wells.
 Design/ Methodology/ Approach: Sulphate determined by measuring longitudinal change cube specimens that were cured sodium solution for 21 days. Cube with varied concentrations (0%, 0.3%, 0.6%, 0.9% and 1.2%) study. Five separate solutions maintaine...
