Characterization and properties of blended cement matrices containing activated bamboo leaf wastes
(ELSEVIER SCI LTDOXFORD, 2012-10)
The worldwide production of bamboo generates large volumes of leaf wastes, which are deposited in landfills or burned in an uncontrolled manner, with negative effects in the environment. The ash obtained by calcining of ...
Blended cements with limestone filler and kaolinitic calcined clay: Filler and pozzolanic effects
(American Society of Civil Engineers, 2017-09)
In this paper, binary and ternary blended cements (BC) based on calcined clay (CC, 0-30%) obtained from low-grade kaolinitic clay and limestone filler (LF, 0-10%) were developed and the interaction between the filler effect ...
Investigating the possible usage of elephant grass ash to manufacture the eco-friendly binary cements
(Elsevier B.V., 2016-03-10)
In recent years, agro-industrial residues are focusing attention worldwide as a new source of pozzolans; in Brazil one of the wastes generated from agro-industrial activities comes from elephant grass that is cultivated ...
Gypsum hemihydrate-cement blends to improve renderings durability

Kaolinitic calcined clays - Portland cement system: Hydration and properties
This paper examines the influence of type of kaolinite in the raw clay on the performance of calcined clays as supplementary cementing materials. Two kaolinitic clays were characterized, calcined then ground and used as ...
Effect of cement composition on the early hydration of blended cements with natural zeolite
This paper studies the addition (0–40% w/w) of natural zeolite (NZ, 84% clinoptilolite) in blended cements made with Portland cement (PC) with low and medium C3A content. The isothermal calorimetry was used to understand ...
Measuring the eco-efficiency of cement use
(ELSEVIER SCI LTD, 2010)
At present, the cement industry generates approximately 5% of the world`s anthropogenic CO(2) emissions. This share is expected to increase since demand for cement based products is forecast to multiply by a factor of 2.5 ...
