Physico-Chemical Characteristics Of Cement Manufactured With Artificial Pozzolan (Waste Brick)

open access: yes, 2009
The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial ...

Plant responses to urban gradients: Extinction, plasticity, adaptation

open access: yesJournal of Ecology, Volume 112, Issue 12, Page 2861-2875, December 2024.
Herbaceous plants often change their morphology in response to urban conditions: grass cutting, altered soils, warmer temperatures and being surrounded by tightly‐packed buildings. These changes are sometimes hereditary, which suggests that city management and planning affect the ability of plants to survive and evolve in urban environments.
