The quality of cement is one of the important factors which materially contribute to the strength and durability of structural concrete. Different brands of Portland cement are used in Libya by local contractors for various construction work. However, no comparative study has been made undertaken hitherto to investigate the mechanical and physical properties of the various brands of cement. Thi...

Excessive soil acidity is known to have potential negative impacts on crop production. The chemical and physical characteristics of a liming material determine its capacity to neutralize soil acidity. The material CaCO3 equivalent (CCE) and fineness effectiveness estimates are included in effective CCE (ECCE) assessments of a material’s liming value and to decide application rates. The objectiv...

The unique minerals of the Au-Pd-Hg system in gold grains from heavy concentrates Itchayvayam placers and watercourses draining ore samples Barany outcrop at mafic–ultramafic complex (Kamchatka, Russia) were investigated. Gold contain substitution structures formed by Pd,Hg-rich low-fineness (Au0.59–0.52Pd0.24–0.25Hg0.17–0.23, 580‰–660‰) Pd,Hg-poor high-fineness (Au0.94–0.90Pd0.02–0.04Hg0.03, 9...

A detailed restriction fragment length polymorphism map was used to determine the chromosomal locations and subgenomic distributions of quantitative trait loci (QTLs) segregating in a cross between cultivars of allotetraploid (AADD) Gossypium hirsutum (‘‘Upland’’ cotton) and Gossypium barbadense (‘‘Sea Island,’’ ‘‘Pima,’’ or ‘‘Egyptian’’ cotton) that differ markedly in the quality and quantity ...

A locallic version of Hager’s metric-fine spaces is presented. A general definition of A-fineness is given and various special cases are considered, notably A = all metric frames, A = complete metric frames. Their interactions with each other, quotients, separability, completion and other topological properties are discussed.

Plant growth regulators such as mepiquat chloride (MC) and chlormequat (CCC) are used to establish the balance between vegetative generative in cotton. This study was conducted compare different doses application time of CCC with MC un-treatment (control). The seven treatments including control (non-treatment), T1 (three sprays chloride), T2 (two T3 (0.4 L ha-1 CCC), T4 (0.5 T5 (0.6 CCC) T6 (0....

The physical and mechanical properties of German Angora rabbit fiber obtained from the Northeast region India were studied. fineness, staple length, diameter, medullation overall fleece 0.22 ± 0.04 tex, 09.10 2.21 cm, 23.5 1.04 µm, 85.46 1.23%, respectively. cross-sectional shape was found elliptical to oval, average tenacity, breaking elongation, specific work rupture, initial modulus 24.78 11...

Abstract The use of glass and brick powder waste as supplementary cementious material provides an effective approach to produce concrete in order effectively save resources solve environmental pollution problems. This study shows the evolution preparation eco-friendly self-compacting mortar (SCM) with various fineness levels replacement ratios crushed calcined waste. Cement was replaced by weig...
