Elastic Properties of Concrete Incorporating Ogugu Lateritic Sand as Fine Aggregate
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.This study investigates the substitution of conventional fine aggregate with Ogugu lateritic sand in concrete grades 25 and 50, focusing on elastic behavior and strength development. The results show that laterized concrete achieves significant strength gains over time, with grade 25 compressive strength increasing from 14.11 N/mm2 at 3 days to 32.27 N/

Stabilisation of Sulfide‐Bearing Clays as a New Building Ground
European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.ABSTRACT Fine‐grained, sulfide‐bearing marine clays are found along the Finnish coastline. When excavated and exposed to air, the sulfides within these soils react with oxygen to form sulfuric acid. Such soils are classified as hypersulfidic soils.

Hydration study of Belite-Alite Calcium Sulfoaluminate (BACSA) cement blended with fly ash [PDF]
, 2015 The main objective of this work is to understand the effect of the addition of fly ash (0, 15 and 30 wt%) in the hydration of a BACSA cement paste (water/cement=0.4) prepared with 12 wt% of anhydrite. The pastes were characterized, at different hydration

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Solidification/stabilization (S/S) is a widely adopted remediation technique for contaminated soils. However, how to efficiently and economically modify contaminated soil remains challenging. In this study, secondary aluminum ash slag (AAS) was employed as a novel stabilizer for the S/S treatment of lead (Pb) and zinc (Zn) contaminated soils.

Mechanical strength and corrosion detection of pozzolanic cement
HBRC Journal, 2013 AbstractVarious pozzolanic cement pastes based on ordinary Portland cement (OPC), granulated blast furnace slag (GBFS) and metakaolin (MK) were studied. Mixes were prepared using a water/solid ratio (W/S) of 0.25wt.%. Hydration characteristics of the different hardened cement pastes were investigated via the examination of chemically-combined water ...
