Effect of bitumen wax on asphalt mixture performance.
November 1, 2007... Abstract This paper mainly deals with waxes which are naturally present in bitumens, and does not include synthetic waxes that sometimes are proposed as bitumen additives. The main objectives were to study the rheological effect of bitumen...

Compressive strength characteristics of cement stabilized rammed earth walls.
November 1, 2007... Abstract In order to minimize the environmental impacts caused by over exploitation of natural resources for the production of building material, the possibility of using cement stabilized rammed earth for load-bearing walls has been...

Defects of non-loadbearing masonry walls due to partial basal supports.
November 1, 2007... Abstract The attempts to reduce heat transmission heterogeneity all over the external surface of building envelopes include several recommendations about external protection of concrete structures with thin clay brick walls. This procedure...

Experimental investigation of load carrying capacity of the slender reinforced concrete columns wrapped with FRP.(fiber reinforced polymer)
November 1, 2007... Abstract Axial compression test was conducted on 6 elliptical modified rectangular slender reinforced concrete columns wrapped with FRP, with a slenderness ratio L/b ranging between 4.5 and 17.5. The test result showed that the effect of...

The problem of shear in RC beams strengthened with CFRP laminates.(Reinforced Concrete)(Carbon Fibre Reinforced Polymer)
November 1, 2007... Abstract The effectiveness of externally bonded reinforcement of a strengthened Reinforced Concrete (RC) beam subjected to a shear-dominant loading regime is not well-established. The aim of this paper is to clarify the structural...

Red ceramic industrial products incorporated with oily wastes.
November 1, 2007... Abstract An industrial scale investigation into the effects of oily wastes incorporated into different red ceramic products for building construction was carried out for the first time. The oily wastes were a crude sludge derived from...

Durability of cementing binders based on fly ash and other wastes.
November 1, 2007... Abstract The paper deals with the cementitious binders produced by blending 60-70% fly ash with fluorogypsum, hydrated lime sludge, with and without Portland cement and chemical activator in different proportions. Data show that strength...

Study on early-age cracking of cement-based materials with superplasticizers.
November 1, 2007... Abstract The addition of superplasticizers is an important approach to prepare high performance cement-based materials. The effect of polynaphthalene series superplasticizer (PNS) and polycarboxylate type superplasticizer (PC) on early-age...
