Knowledge and Experience of Menopause - A Rural Based Study in Aligarhjournal ijrtem
ABSTRACT: The menopause is a transitional phase in women’s life.The level of oestrogen is decreased ,because of which a variety of symptoms such as hot flushes, mucosal dryness, excessive sweating, emotional fluctuations, psychoses, decr-eased strength and calcification of bones occurs. Attitudes, perception and expectations are part of the psychosocial phenomenon surrounding menopause. Natural menopause is diagnosed after 12 months of amenorrhoea not associated with a pathological cause. Menopause is a gradual process that lasts for about 2 years, called climacteric. It is normal and should not be taken as a disease or syndrome. The aim of this study was to find out the knowledge and experience of menopausal symptoms among women who had attained menopause
Strength of Concrete Containing Basalt FibreIJERA Editor
This paper presents the comparative study of effect of basalt fibre on compressive and split tensile strength of M40 grade concrete. The basalt fibre was mixed in concrete by (0.5%, 1%, and 1.5%) of its total weight of cement in concrete. Results indicated that the strength increases with increase of basalt fibre content up to 1.0% beyond that there is a reduction in strength on increasing basalt fibre. The results show that the concrete specimen with 1.0% of basalt fibre gives better performance when it compared with 0.5%and 1.5% basalt fibre mix in concrete specimens.
Strength Evaluation of Steel-Nylon Hybrid Fibre Reinforced ConcreteIJERA Editor
When fibres like steel, glass, polypropylene, nylon, carbon, aramid, polyester, jute, etc are mixed with concrete known as fibre reinforced concrete. To overcome the deficiencies of concrete; fibres are added to improve the performance of concrete. In this research hybrid reinforced concrete is made by using steel and nylon 6 fibres. The inclusion of both steel and nylon 6 fibres are used in order to combine the benefits of both fibers; structural improvements provided by steel fibers and the resistance to plastic shrinkage improvements provided by nylon fibers. So the aim of this project is to investigate the mechanical properties (compressive strength, flexure strength and split tensile strength) of hybrid fiber reinforced concrete under compression, flexure & tension. The total volume of fibre was taken 0.75 % of total volume of concrete. In this experimental work, four different concrete mix proportions were casted with fibres and one mix without fibres. Four different mix combinations of steel- nylon 6 fibres were 100-00%, 75-25%, 50-50% and 25-75%. Superplasticizer was used in all mixes to make concrete more workable. The results shown that compressive, split tensile and flexural strength of hybrid fibre reinforced concrete increase by increasing quantity of steel and nylon 6 fibres. The increase in compressive and tensile strength due to incorporation of steel fibre is greater than that of using nylon fibre. For the nylon 6 fibres, adding more fibres into the concrete has a limited improvement on splitting tensile strength. Inclusion of nylon 6 fibres along with steel fibres results in considerable improvement in flexural strength as compared to solo steel fibre.
EFFECT OF STEEL AND POLYPROPYLENE FIBER ON MECHANICAL PROPERTIES OF CONCRETEIAEME Publication
This experimental work describes the mechanical properties of Hybrid Fibre Reinforced concrete(HFRC).HFRC is prepared by adding any two fibres to the conventional concrete to make it a composite mixture and that derives benefits from each of the added fibre and exhibits significant response. The fibres which are used in the present experimental work is steel fibres and polypropylene fibres. Here the polypropylene fibres helps in resists initial cracks and shrinkage ,steel fibres helps in increase the strength of concrete. In present work M30 grade of concrete can be prepared according to the IS 10262:2009 reference code. these steel and polypropylene fibres are added by 50% each with different hybridization from 0% to 1.5%.For calculating strength parameters specimens are casted and cured for 28 days and tested in the lab for Compressive Test, Tensile Test, Flexural test. From the present investigation the strength parameter increases with the percentage of increase in fibre. Therefore here the hybrid ratio of 1.5% gives the more result when compared to other hybrid ratio.

STUDY OF STRENGTH PROPERTIES OF POLYESTER FIBRE REINFORCED CONCRETEJournal For Research
Fiber Reinforced Concrete" is relatively a new construction material developed through extensive research and development work during the last two decades. Fiber Reinforced Concrete (FRC) is defined as composite material which consists of conventional concrete reinforced by randomly dispersed short length fibers of specific geometry, made of steel, synthetic (polymeric) or natural fibers. Plain cement concrete has very low tensile strength and causes formation of micro cracks in stressed and unstressed states of concrete. Also, it has a low strain at fracture and brittleness with less ductility especially in case of High Performance Concrete. Fiber Reinforced Concrete is the answer to modify these properties of Plain Concrete. The recent development of Secondary reinforcement in Concrete in various fields has provided a strong technical base for improving the quality of the material. To overcome the deficiencies fibers are used as secondary reinforcement. FRC is Portland cement concrete reinforced with more or less randomly distributed fibers. The choice of fibers varies from synthetic organic materials such as polypropylene or carbon, synthetic inorganic such as steel or polyster, natural organic such as cellulose or sisal to natural inorganic asbestos. The interaction between the fiber and concrete matrix is the fundamental property that affects the performance of a cement based fiber composite materials. An understanding of this interaction is needed for forecasting the fiber contribution and for predicting the behavior of such composites. In present investigation concrete with addition of polyester fiber Recron 3s at various at dosages of 0.25%, 0.50%, 0.75% and 1.00% by weight of cement in the mix design is studied to find the optimum dosage of Polyster fiber for concrete.
