New Building Envelope Materials for Energy Saving and Sustainability

Journal of Engineering, Volume 2026, Issue 1, 2026.
The hygrothermal performance of building envelopes critically influences indoor comfort and energy demand, especially in warm climates where air conditioning represents a major energy use. This study evaluates a composite earth‐based brick incorporating crushed limestone aggregates, lightly stabilized with 8% cement and optimized for Mediterranean ...

Influence of a natural pozzolana on the properties of high performance mortar

, 2004
Certain finely ground mineral admixtures, such as blast furnace slag, pozzolana and limestone, influence, to a greater or lesser extent, the chemical and physico-mechanical properties of concrete/mortar.

Mechanical Performance of Black Cotton Soil Stabilised With Bagasse Ash Incorporating Limestone Calcined Clay Cement Under Varied Loading Conditions

Journal of Engineering, Volume 2026, Issue 1, 2026.
Construction of geotechnical infrastructures in tropical regions characterised by black cotton soil (BCS) presents major engineering challenges due to its high swelling and shrinkage potential. Bagasse ash (BA) incorporating limestone calcined clay cement (LC3) has emerged as a promising stabilisation approach to enhance the performance of foundations ...

Effect of Cement Substitute Produced From Sustainable Materials on the Setting Time of the Mortar

Journal of Engineering, Volume 2026, Issue 1, 2026.
Present research is aimed at reducing the carbon footprint of Portland cement, which contributes to global warming. Its objective is to produce concrete made from sustainable, eco‐friendly materials (slag and lime dust) that have properties similar to cement and provide a double benefit by reducing waste in landfills and reducing cement pollution.

An Experimental Study on Portland Pozzolana Cement Mixed with Natural Hydrocolloids

Journal of Applied Engineering Sciences
Abstract To make a structure sturdier, the construction materials must be of higher quality. To enhance the structural qualities of fresh concrete, or improve the properties of hardened concrete, additives are added to concrete during the mixing process.

Physicochemical properties of silicate-calcium micro-filler obtained by thermolysis of calcium hydrosilicates stabilized with sucrose

MATEC Web of Conferences, 2018
Calcium hydrosilicates obtained by grinding a mixture of natural pozzolana (flask), CaO and a sucrose solution are characterized by the ability to self-disperse during heat treatment to form a highly dispersed silicate-calcium dispersion (SCD).
