“…It should be noted that the use of 20 wt.% of PSP significantly reduces the density of B-CEBs at 23%. A similar reduction (around 25%) was reported by Khoudja et al [36] during the stabilization of adobe with 10% of date palm waste. Sore et al [8] stabilized CEB using cement and geopolymer and found the density ranging in 1600 -1900 kg/m 3 .…”

“…Lertwattanaruk and Suntijitto [42] studied the compressive strength of palm oil fibre reinforced cement mortar. They also reported a similar result with Khoudja et al [55]. A total of 15% of the palm oil fibre-contained specimen resulted in only 60% of compressive strength compared with the control specimen.…”

Cementitious materials are widely used in the construction industry. These materials have high compressive strength and huge environmental effects but low tensile and flexural strength. Thus, researching these materials to make them environmentally friendly is very important in terms of the sustainable development of the construction industry. In recent years, the amount of research about cementitious composites reinforced with natural fibre has increased annually. This review paper was presented to understand the latest research progress on these fibres and the needs of future research to encourage the construction industry to apply these materials. The optimum dosage of natural fibre depending on the purposes can improve the physical, mechanical and thermal properties of cementitious composites, and natural fibre is highly expected to become an alternative material of synthetic fibres, such as steel, plastic and carbon fibre.

“…The results of the laboratory tests are shown in Table 1. The thermal conductivity value was relatively low, compared to relevant values reported in the literature [11,12]; this can be attributed to the high content of straw fibres in the mix-design, which is confirmed by the low density of the adobes studied. The open porosity value was also high; this confirms the low values of density and thermal conductivity and the high value of capillary absorption coefficient reported.…”

Vernacular architecture incorporates many cooling and heating passive design strategies related to the structural envelope, the different architectural arrangements and the way of living of the inhabitants. Adobe walls are considered to be high thermal mass masonries, as they have the ability to store thermal energy. The high thermal inertia of these materials regulates indoor temperature variations through considerable time lags, thus contributing to the improvement of thermal comfort conditions. This study deals with the environmental behaviour of an adobe historic building in the rural area of Nicosia, Cyprus. The aim of this study is the investigation of the hygrothermal performance of the external adobe masonry walls of the structure under study. For this purpose, in-situ long-term monitoring is currently being carried out, focusing on the indoor and outdoor environmental conditions of a south wall of a room which has two exposed surfaces, the north towards the street and the south towards a courtyard. The south wall is being monitored with temperature/moisture sensors, installed at various locations along its thickness and height. In situ monitoring is complemented with laboratory measurements of the thermophysical (thermal conductivity, porosity, and sorptivity) properties of the main masonry material (adobes). Rising damp height, time of wetness, thermal inertia and decrement factor have all been calculated based on the laboratory and in-situ measurements. The results are analysed in terms of existing standards and analytical equations. The findings of this research may be used to evaluate the overall thermal performance of historic adobe buildings and the effectiveness of adobe walls in the improvement of indoor comfort conditions.
