Influence of PZT insertion on Portland cement curing process and piezoelectric properties of 0–3 cement-based composites by impedance spectroscopy
(2020-03-30)
0–3 Cement-based piezoelectric composites were produced. It was verified that not only the piezoelectric properties of the composites, but also the influence of piezoelectric phase in the cement paste curing process. The ...
Nanoindentation study of the interfacial zone between cellulose fiber and cement matrix in extruded composites
(2018-01-01)
The present study shows the application of the nanoindentation technique to evaluate the properties of the cellulose fiber-cement matrix interfacial zone in composites prepared with an auger extruder. The degree of strength ...
OBTAINMENT OF HYBRID COMPOSITES BASED ON HYDROGEL AND PORTLAND CEMENT
(Soc Brasileira Quimica, 2016-02-01)
In this study, a novel hybrid composite based on biodegradable hydrogel and Portland cement with promising technological properties was reported. In the first step, a full 2(3) with central point factorial design was ...
A new treatment for coconut fibers to improve the properties of cement-based composites – Combined effect of natural latex/pozzolanic materials
(2017-07-01)
This paper presents the results of experimental study with a new coconut fiber-cement composite (CFC). To obtain a material with improved performance in order to decrease the amount of calcium hydroxide present on the fiber ...

Evaluation of cellulosic pulps treated by hornification as reinforcement of cementitious composites
(Elsevier B.V., 2015-12-15)
This study evaluated the effect of the homification process on cellulosic fibers of bleached pine and unbleached eucalyptus with in order to improve its durability and volume stability to be used as reinforcement in ...
Cellulose modified fibres in cement based composites
(ELSEVIER SCI LTD, 2009)
The objective of the present work is to evaluate the effect of surface modification of cellulose pulp fibres on the mechanical and microstructure of fibre-cement composites. Surface modification of the cellulose pulps was ...
Eucalyptus pulp fibres as alternative reinforcement to engineered cement-based composites
(ELSEVIER SCIENCE BV, 2010)
This paper evaluates the advantages of using hardwood short fibre pulp (eucalyptus) as alternative to softwood long fibre pulp (pinus) and polymer fibres, traditionally used in reinforcement of cement-based materials. The ...
Rationalizing the effect of accelerated carbonation and accelerated ageing on transition zone of cellulose fibers in cement based composites
