Bond strength/disbonding behavior and dimensional stability of wood materials with different adhesives

In this paper, a new early strength tile adhesive is prepared by using α- high strength gypsum and its properties are discussed. The research methods refer to relevant Chinese standards. The results show that the tensile bond strength of the adhesive can reach 0.6 MPa in one day and 1.5 MPa in 7 days, which is close to 80% of 28-day strength. It is indicating that the adhesive has high bond strength, rapid strength development, and high dimensional stability. It effectively solves the problems that the traditional cement-based tile adhesive is prone to hollowing, falling off, and cracking. Additionally, no interface treatment is required during the using process of this gypsum-based adhesive.

The effect of particle composition made of bamboo and water hyacinth on the dimensional stability and mechanical properties of resulted oriented strand boards (OSB) were investigated. Three layered boards were made from bamboo and water hyacinth in which bamboo strand was used as face/back layer and water hyacinth strand was used as core layer. The boards were manufactured using three levels of bamboo and water hyacinth compositions (50:50, 60:40 and 70:30) with 6 % isocyanate based on the strand oven dry weight. The results showed that dimensional stability of the OSB decreased with the increase of composition of water hyacinth strand on core layer. A higher composition of bamboo strand as face/back layer compared to water hyacinth strand resulted in increased modulus of elasticity and internal bond strength, but decreased the modulus of rupture. The bamboo and water hyacinth composition of 70:30 compositions showed better properties than other compositions. Key words: Bamboo, water hyacinth, composition, OSB

Structural Failures

In modern days for structures in coastal areas it has been observed that the premature structural failures are occurs due to corrosion of the reinforcements of the designed structural member. The corrosion causes the structural damage which in turn leads to reduction in the bearing capacity of the concerned structural members. The aim of this study was to study the effect of partial replacement of fly ash to minimize the corrosion effect. Beams were designed and corroded by using artificial method known accelerated corrosion method. The beams were then tested for flexural and bond strength. Also the weight loss of the reinforced bars was been determined using electrical resistivity method. The fly ash will replace by 10% and 15%.The strength will calculate at varying percentage of corrosion at 10% and 15%. Beams will cast at M25 grade concrete. The flexural strength will test by using UTM and the bond strength will calculate using pullout test.
