This paper aims to study the mechanical behavior and surface chemistry in relationship with moisture content of Iroko (Milicia excelsa), Bilinga (Nauclea diderrichii), Tali (Erythrophleum suaveolens). Mechanical characterization was done experimentally using tensile bending tests. Chemical semi quantitative analysis wood at 10%, 15%, 20% 30% investigated attenuated total reflectance Fourier transform infrared spectroscopy. The main chemical functions involved by presence water were...
Artisans in the Sudano-Sahelian zone of Cameroon make abundant use adobes formulated from red millet fibers for construction houses. However, scientific data are missing literature to provide necessary information understanding thermomechanical characteristics and durability these materials. Adobe bricks used this paper soil with 0, 1, 2, 3, 4 % waste. The samples characterized by geotechnical, mechanical, thermal, laboratory tests. Experimental measurements mechanical thermal show that can...
Neem fibers are traditionally added as reinforcements in adobes. Laboratory experiments including, compressive strength, three-point bending water absorption, erosion and thermal conductivity were carried out on adobes made with soil reinforced two neem types (straw leaves) at 0, 1, 2, 3 4%. It has been found that mechanical, thermal, durability properties of globally improved. Furthermore, leaves contribute strongly comfort but their use a negative effect durability. Nevertheless, suitable...
The development of glulam may give complementary, added-value to an important part the timber production in Congo Basin. Nevertheless, high humidity which these timbers operate cause problems such as cracks and severe deformations if they are not suitably bonded. Moreover, there is a lack knowledge concerning refined design bondlines assembling from Basin hardwoods. We investigated durability, mechanical strength, variability features bondlines, manufactured under higher moisture conditions....
This paper aims to study the mechanical, thermal and hygroscopic behavior of Okan (Cylicodiscus gabunensis) Ayous (Triplochiton scleroxylon), two African hardwood species grown in southern Cameroon. The mechanical characterization wood at 10%, 15%, 20%, 25% 30% was investigated using tensile bending tests. parameters were measured same moisture content levels by asymmetrical hot plate method. Sorption isotherms obtained static gravimetric Mechanical properties decreased with content. wood,...
An experimental study was carried out to evaluate the feasibility of using concrete compositions containing waste wood for structural and non-structural building applications. First, inert aggregates used in composite design were characterized. Five a reference, 50% 100% particles then produced characterized terms physical mechanical performance (e.g., apparent density, abrasion, compressive strength, flexural strength). The selected specimens additional tests. These included water...
