TL;DR: In this article, a sisal fiber enhanced coral concrete and a preparation method for its preparation is presented, wherein the concrete consists of coralcrete and sisal fibers, wherein coral concrete is in the level C30, and each cubic meter of the coral concrete consisting of 315-360 kilograms of cement, 90-135 kilograms of silica fume, 830 kilograms of sand, 716 kilograms of coral and 180 kilograms of seawater.
Abstract: The invention discloses sisal fiber enhanced coral concrete and a preparation method thereof. The concrete consists of coral concrete and sisal fibers, wherein the coral concrete is in the level C30, and each cubic meter of the coral concrete consists of 315-360 kilograms of cement, 90-135 kilograms of silica fume, 830 kilograms of sand, 716 kilograms of coral and 180 kilograms of seawater; the mass sum of the cement and the silica fume is 450 kilograms. The sisal fiber enhanced coral concrete is prepared by pouring cement, silica fume, sand and coral into an agitating machine for agitating, adding the sisal fibers for uniform dry agitating, and then adding the seawater for agitating. The concrete disclosed by the invention is high in splitting tensile strength and breaking strength, and has the characteristics of energy conservation, environment friendliness, low manufacturing cost, low heat conduction property, zero electromagnetic interference and the like.

TL;DR: In this article, a composite bacteria method was proposed for extracting tigogenin and/or hecogenin from agave sisal dregs, which comprises steps as follows: pectin and saponin are hydrolyzed with Pectinase and cellulase, while the viscosity of sisal Dregs is reduced, and then the released saponins is effectively degraded by the aid of compound enzyme produced from mould composition after fermentation.
Abstract: The invention discloses a method for extracting tigogenin and/or hecogenin with a composite bacteria method. The method comprises steps as follows: pectin in agave sisal dregs is hydrolyzed with pectinase and cellulase, saponin in the sisal dregs is released while the viscosity of the sisal dregs is reduced, and then the released saponin is effectively degraded by the aid of compound enzyme produced from mould composition after fermentation. The method can be used for extracting tigogenin or hecogenin from the sisal dregs, can be used for extracting tigogenin and hecogenin from the sisal dregs simultaneously, and has the advantages of simplicity in operation, mild extraction conditions, small environmental pollution, high product yield and purity, low cost and the like.

TL;DR: In this paper, weibull statistics were used to quantify the degree of variability in fiber strength at different gage lengths and fiber-matrix pull-out behavior was evaluated at several curing ages and embedded lengths.
Abstract: Durable sisal fiber cement composites reinforced with long unidirectional aligned fibers were developed and their mechanical behavior was characterized in a multi-scale level. Tensile tests were performed in individual sisal fibers. Weibull statistics were used to quantify the degree of variability in fiber strength at different gage lengths. The fiber-matrix pull-out behavior was evaluated at several curing ages and embedded lengths. The composite’s mechanical response was measured under direct tension while crack formation was investigated using a high resolution image capturing procedure. Crack spacing was measured using image analysis and correlated with the applied strain under both the tensile and bending response.

TL;DR: Results showed that the interaction of sisal dust, sisal fibres and sisal decortications leaves wastes substrates with chicken manure at varying concentrations, produced a highly significant effect on cap lengths and diameters, stipe lengths and diameter and dry weights of C.lat.
Abstract: The effect of the interaction of varying chicken manure supplement levels with three different solid sisal wastes substrates on sporocarp cap lengths and diameters, stipe lengths and diameters and dry weights of Coprinus cinereus (Schaeff) S. Gray s.lat Coprinus cinereus (Schaeff) S. Gray s.lat is an indigenous Tanzanian edible and medicinal mushroom, which grows in the wild on decomposed sisal wastes heaps. In the laboratory, it was cultivated on three types of sisal wastes substrates each supplemented with varying chicken manure concentrations 0, 5, 10, 15, 20 and 25% using solid-state fermentation bioreactors. The results showed that the interaction of sisal dust, sisal fibres and sisal decortications leaves wastes substrates with chicken manure at varying concentrations, produced a highly significant effect (p < 0.05) on cap lengths and diameters, stipe lengths and diameters and dry weights of C. cinereus (Schaeff) S. Gray s.lat. The interactions of sisal dust waste with 5% chicken manure concentration induced longest mean cap length and widest mean cap diameter. On the other hand, the interaction of sisal leaves decortications wastes with 25% chicken manure concentration produced heaviest sporocarps mean dry weight. These findings for the first time illustrate importance of chicken manure supplementation in C. cinereus (Schaeff) S. Gray s.lat cultivation on sisal decortications wastes substrates. Key words : Coprinus cinereus, chicken manure, solid sisal wastes, sporocarps, pileus, stipe.
