Clay soils can exhibit swelling and settlement behaviour when interacted with water. The clays located in road infrastructure damage the pavement cause cracks because of and/or clays. freezing-thawing processes clay increase damages pavement. Additionally, strength losses occur. Weak be improved using various soil improvement techniques or without additives. In this study, liquid polymers (poly...

Peat normally has high organic matter content and is generally associated with high compressibility and high magnitude and rates of creep. It may also be associated with poor strength characteristics and a risk of large deformation. The main specifications in the peat nature are the presence of acidic or less commonly alkaline media, combined with a high level of ground water. One of the most c...

AIMS To examine organic neem compounds for their effective growth inhibition of saprotrophic soft-rot fungi on anthracite bricks bound with collagen and lignin for use in iron foundry cupolas as an alternative fuel source. METHODS AND RESULTS Azadirachtin, crude neem oil (NO), and clarified neem oil extract (CNO) were combined with copper to inhibit the growth of the soft-rot fungus, Chaetomi...

In this study the performance of clay nano-particles on the soil reinforced with Polypropylene fibers (PP-fiber) has been investigated. Also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. Soil mixtures were modified with varying percentages of nanoclay and Fibers. Unconfined compressive strength (UCS), Compac...

This paper outlines a theoretical approach for predicting the onset of detonation in unconfined turbulent flames. Two basic assumuptions are made: 1) the gradient mechanism is the inherent mechanism that leads to DDT in unconfined conditions, and 2) the sole mechanism for preparing the gradient in induction time is by turbulent mixing and local flame quenching. The criterion for DDT is derived ...

Phosphogypsum (PG), as a by-product of the production phosphoric acid, faces problems large annual output and difficult treatment. There is demand for fillers in process road paving, which may be an effective method utilization PG resources. In this study, three proportions phosphogypsum–lime–fly ash (PLF) mixture were designed, first, according to orthogonal tests. The comprehensive performanc...

Many of the improvised explosive devices received at the Forensic Explosives Laboratory (FEL) contain pyrotechnic or home-made explosive mixtures as the explosive charge. Pyrotechnic residues contain a complex mixture of combustion products and unconsumed material. It has been reported that pyrotechnic residues comprise characteristic particles, similar to the formation of gunshot residue parti...

The biphasic poroviscoelastic (BPVE) model was curve fit to the simultaneous relaxation of reaction force and lateral displacement exhibited by articular cartilage in unconfined compression (n=18). Model predictions were also made for the relaxation observed in reaction force during indentation with a porous plane-ended metal indenter (n=4), indentation with a nonporous plane ended metal indent...
