Considerations about the use of lime-cement mortars for render conservation purposes [PDF]

, 2011
Some investigations about conservation renders points out that Portland cement based mortars should be avoided and should be replaced by lime-pozzolan mortars.

Performance evaluation of blended cement mortar with supplementary cementitious materials: from pozzolans to industrial wastes

Reviews on Advanced Materials Science
This investigation aims to examine the behavior of natural and manufactured pozzolans, as well as the properties of blended mortars. Eco-friendly building materials are gaining the attention of researchers worldwide, as they are made from supplementary ...

Sustainable infrastructure development through use of calcined excavated waste clay as a supplementary cementitious material [PDF]

, 2017
Major infrastructure development projects in London produce large quantities of London clay and use significant volumes of concrete. Portland cement (CEM I) in concrete is normally partially replaced by supplementary cementitious materials such as ground

Impact on flow characteristics of concrete produced with artificial sand and many pozzolanic materials

Discover Civil Engineering
Abstract Overuse of cement and natural sand has damaging impacts on the environment and society. To solve this, manufactured sand can be used in place of natural sand and cement, together with pozzolanic materials—industrial waste byproducts such as metakaolin, GGBFS, silica fume, and fly ash.

Performance characteristics of concrete containing natural and artificial pozzolans

, 2011
In this research, the effects of natural zeolite (NZ) and rice stalk ash (RSA) as Portland cement replacement materials on properties of cement were investigated using three different combinations (NZ, RSA, NZ+RSA) of tests. These materials were used as substituted for Portland cement in different proportions, and then physical, mechanical and thermal ...
