“…The rupture envelope, which is determined by the strength's test under conditions, does not parallel the normal tension axis after a point, and the ground behaves both cohesively and internally. Total tension analysis method can be applied to cover this condition and to analyze stability by sliding mass divided into a certain number of vertical slices [12,[35][36][37]. Bishop method: in this method, as in all stability problems, the initial shift is taken as post-equilibrium equations are taken out as if the slope is in the limit equilibrium.…”

The Rock Fallings, Shale Slopes Stability, and Stability Risk Assessment in Şırnak open pit asphaltite mining should be searched in detail and improved in several coal mining sites in Şırnak Province, reaching over 120 m height with 60-65 degree shale slopes, developing major landslide in the open pit Şırnak open pit coal mining. The rock fallings endangered the mining safety in recent years. This research provided stability patterns and cementing method strengthening cracks. The stages of experimentation explored the geo-technical characteristics and geoological formation. Fort his aim, four different open pit mining areas with similar geotechnical conditions, two main strengthening methods, and patterns of researches were developed. Firstly, data on landslides and rock dynamics over explosions were followed, and secondly, as happened commonly in the past, the same geological, geomorphologic, hydrological, climatic conditions were taken. Anchorage pile strengthenıng of slopes and cementing falling stone blocks were performed by mixtures of melted waste plastics/asphalt and fly ash for stability of higher slopes over 120 m height and over 65 degree in asphaltite mining site in Silopi and Avgamasya open pit No.1 mining site in Şırnak were carried out. On the other hand, due to that creep style rock falling from top of slopes, those melted polymer cementing of anchorage bolting and cracks, to eliminate those falling failure types and features, will be advantageous. The unconditional expectations related to this study was also defined for this region, such as the influence of the ground water, rock cracks and slope design, and explosion exchange dynamics leading to landslide. GEO5 software and manual stability analysis showed high risk area for plotting.

“…It is available in different types, sizes, and colors, and can reduce concrete dead weight. Similar to other pozzolanic materials, such as silica fume and fly ash, substitution with zeolite can improve the strength of concrete via the pozzolanic reaction with Ca(OH) 2 . It can reduce the bleeding, segregation, and delamination of fresh concrete, facilitate pumping processes, decrease the permeability of hardened concrete, enhance durability (especially alkaliaggregate reactivity), increase concrete strength, and minimize the cracking in concrete caused by autogenous-shrinkage.…”

“…Corroborating this view, it was generally observed in this research that increase of masonry density reduced the water penetration of LCHC blocks. For thermal comfort as affected by the building envelope, water content of masonry blocks should be kept as low as possible [2]. Although no limiting value for water absorption of concrete masonry units was stipulated in BS 6073, it is usually accepted that less than 300 kg/m 3 of water absorption for individual masonry unit is more appropriate for the partitioning and curtain walls in buildings.…”

Lightweight cellular hollow concrete (LCHC) block is a type of masonry unit manufactured by precast technique. LCHC blocks are produced by the mixing of Portland cement, volcanic tuff, expanded clay and diatomite for building applications. LCHC blocks are lightweight and being frequent cellular hollow cleavages, give excellent thermal and acoustic performance, fire resistance and high weathering resistance to the buildings. In this research work, LCHC blocks with 28 different mix proportions were cast into a mould with vibrocompacting, de-moulded immediately and transferred to a storage area for curing up to 120 days in standard air condition at room temperature. In total, 21 cellular spaces of 10 mm width were placed in the block design. For each mixture, twenty four block specimens were prepared and tested in the air dry condition for compressive strength and water absorption in accordance with BS 1881: Part 116. This paper initially examines how volcanic tuff powder affects the characteristics of lightweight concrete masonry mixtures and investigates the use of quaternary blends containing volcanic tuff, expanded clay, diatomite and Portland cement to produce LCHC blocks for partitioning walls.

The research studied the main consideration of the road construction industry as one of the current consumptions in road aggregate-asphaltite slime mixed asphalt production in Turkey. There was a great awareness of the source of opportunities that polymer-modified mixtures had for road asphalt production (PMA). The shear strength might be developed by microwave processing on compression or during compression. This study searched for the mechanical properties of many mixtures of asphaltite slime and co-polymers by microwave treatment and compression. This study presented the model processing method for the best road cover and showed an overview on the characteristics of polymer-asphalt binders, used in the paving industry. The main fact emphasized was shear resistivity and tension strength development by asphaltite slime made on the regressed relationships of strength and advanced properties of the binder. The relationships between the mixture components of the binder and compression performance of the mixture were also determined.
