Development and properties of composite cement reinforced coconut fiber with the addition of fly ash [PDF]
Journal of Sustainable Cement-Based Materials, 1(4), 186-191
(2012), 2017 In this paper, the effectiveness utilization of agriculture wastes and industrial wastes in the composites cement has been studied in terms of physical and mechanical properties. Twenty weight percent of fly ash and eighty weight percent of sand were added to the composite cement. The different weight percent of coconut fiber (3 wt. %, 6 wt. %, 9 wt. %,

Yield stress of aerated cement paste [PDF]
Cement and Concrete Research 127 (2020) p105922, 2019 Yield stress of aerated cement paste is studied. Samples are prepared by mixing aqueous foam with cement paste, which allows controlling bubble size, gas volume fraction and yield stress of the cement paste. Two distinct behaviors are observed depending on the surfactant used to prepare the precursor aqueous foam: (i) For a surfactant with low ...

Damage Localisation in Fresh Cement Mortar Observed via In Situ (Timelapse) X-ray μCT imaging [PDF]
Cement and Concrete Composites, 2024, 154, 105736, ISSN 0958-9465This paper presents the outcome of a study focused on the evolution of internal damage in fresh cement mortar over 25 hours of hardening. In situ timelapse X-ray computed micro-tomography ({\mu}XCT) imaging method was used to detect internal damage and capture its evolution in cement mortar hardening.
