Barley Straw Ash: Pozzolanic Activity and Comparison with other Natural and Artificial Pozzolans from México

BioResources, 2015
The construction industry is one of the largest and most active growth sectors worldwide. It presents an important environmental impact, and one way to reduce the impact of the construction activity is to substitute pozzolanic materials for ordinary Portland cement.

Mechanical, durability and microstructural characteristics of Portland pozzolan cement (PPC) produced with high volume pumice: Green, cleaner and sustainable cement development [PDF]

, 2023
Nowadays, it is frequently preferred to use pozzolans instead of clinker to reduce the CO2 emissions that increase with cement production. Because in the future, the release of artificial pozzolans, such as fly ash and blast furnace slag, will decrease ...

Performance of silicic pozzolans and Portland cements in their behavior in front of gypsum attack as determined by ASTM C 452-68

Materiales de Construccion, 2013
For this study, ASTM C 452-68 testing was conducted for two years on 54 POZC-silica fume (SF) or diatomites (D and N) (=Z pozzolans), were tested for 2 years, by ASTM C 452-68 method, having determined to their specimens their Vcl(=ΔL(%)/day) .

Is the clay "exchange capacity" concept wholly applicable to pozzolans?

Materiales de Construccion, 2004
One of the most characteristic properties of clays is their "cation exchange capacity", otherwise known as their "exchange capacity ". The research reported in this article shows that for various reasons some natural and artificial pozzolans exhibit this
