Exploring the Effects of Pozzolans on Different types of Portland Cements in Sustainable Cement-Based Applications [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 AbstractThe sources of pozzolans could be natural, industrial and agricultural wastes that are recycled into concrete and mortar applications. There have also been many studies and recommendations guiding the use of blending these pozzolans from multiple sources with cement with the aim of producing more durable, greener and sustainable mortar/concrete.
