“…In the table 8, the 28 days compressive strength of all combinations ranges from 20.64 N/ mm 2 to 32.47 N/ mm 2 . This study shows the concrete made from all the combinations of coarse aggregate sources meet the minimum value of compressive strength which should be given by M20 grade of concrete similar to Aryal and Mishra (2020).…”

The cause of failure of structure made from cement concrete is due to use of low-quality ingredient which is used directly without testing its properties and without studying its suitability in production of different grade of concrete mix. The aim of this study is to presents that the effect of fine aggregates from different sources on compressive strength of cement concrete. For this study four fine aggregate sources were taken. Altogether 48 concrete cubes of M20 grade were prepared from different sixteen combinations of these four fine aggregate sources. The different properties were founded by conducting different laboratory tests for fine aggregates from different sources and the compressive strength test of 48 cubes was conducted.The test results showed that properties of fine aggregate sources such as fineness modulus, loose bulk density, specific gravity, water absorption and Materials Finer than 75 μm were founded in the range of (3.17-3.88), (1508.33-1604.17) kg/m3, (2.57-2.66) %, (1.60-1.92) % and (2.74-7.47) respectively. Compressive strength test of all 48 samples were cross the minimum strength provided by M20 grade and it is ranges from 20.64 N/ mm2 to 32.47 N/ mm2. Different value of mean compressive strength was obtained for all sixteen combinations of aggregates form each other. The fine aggregate from Chisang source achieved more value of average compressive strength when mix with other four different coarse aggregate sample than other three sources. Significance difference in mean compressive strength of concrete made from different fine aggregates source was concluded by the Two-way ANOVA test results. This research work concluded that all four fine aggregate sources used in this study and concrete made from these sources can be used for residential building construction propose and other construction work which required strength provided by M20 grade of nominal mix concrete.

“…Collected materials were tested for physical as well mechanical properties as per standard testing procedures in any convenient Laboratory. Different physical test such as Gradation, Water Absorption, Specific gravity and mechanical tests such as Los Angeles abrasion test, Aggregate Impact value and Aggregate Crushing value [7][8][9]. The following test was carried out on the labs of Infrastructure Development Office, Jhapa.…”

Purpose: There is high demand of aggregates material in the construction industry of Nepal. Till date, river borne aggregate material fulfills major part of the demand. Among various rivers, Biring River is one of the major rivers in Province 1. The objective of this research was to analyze the strength of Aggregate variation along the selected section river basin with a case of Biring. Design/Methodology/Approach: The selected section of Biring River is about 20 Km of Arjundhara Municipality from which 6 sites along the river was selected on the basis of accessibility and deposition for aggregate sources. Lab Test for Physical properties and mechanical properties were conducted on that sample to evaluate their quality for the construction works. Also 18 cubes (3 each from 6 selected sites) were casted to evaluate their compressive strength variation. A linear relationship between the ACV, AIV and LAA value with longitudinal variation of river was established. Also the economic analysis of revenue collected by selling the aggregate of Biring River was done. Findings/Result: After conducting the lab test of physical properties of aggregate, Fineness Modulus, Water Absorption and Specific Gravity were found in the range of (7.16-7.49)%, (0.72-1.15)% and and (2.616-2.712) %. A linear equation for the longitudinal variation in the LAA, AIV and ACV value was established. For a longitudinal variation equation for LAA value y=-0.352x+37.41 ACV value an equation y=-0.212x+29.88 and AIV value an equation y=-0.0189x+27.15 where y = Value of LAA, AIV and ACV value and x = distance in km from upstream origin point. The average compressive strength for 7 and 28 days of all cubes were found to be within standard required. The economic contribution of revenue collected by selling the river bed materials as aggregate of Biring River on the total internal revenue of Arjundhara Municipality was found to be significant that is about 30.86%. Originality/Value: The study contributes that the aggregate material becomes more suitable in their hardness, toughness and strength on moving from upstream towards the downstream along the Biring river. The lower part of stream was assessed to have somewhat better quality of aggregates. Paper Type: Applied Research

“…In this thesis [1] [2], according to earlier research for the damage assessment of a reinforcement concrete building, the problem accounting in consideration of complicated damage factors concerned each other generally has not been showed. With only probability in an area in which judgement of people holds in the design of structure and structural part [3], probability in assessment of the strength of construction materials and the statistical analysis and assessment of the load making its fixed quantity is impossible [4]. In this thesis [5] damage assessment has been performed indicating on fuzzy graph the relation between many factors affect to the damage of the structure.…”

As reinforcement concrete building is composition material which reinforcement bar and concrete work together, effect factors concerned with its damage are countlessly much and interrelationship between them is also very complex and indefiniteness. Until now many researches about the damage assessment of a building has been performed but the problem accounting correctly damage of the reinforcement concrete building by connecting several of damage factors has not yet been solved. In research a method accounting damage of reinforcement concrete building in the fuzzy integral way in consideration of fuzzy property existing in the damage assessment system of it has been newly suggested.
