concentration using the available Halfsize shaking table is used. Two types of filler were considered: limestone (LF) provided from local crushing quarry waste and marble (MF). Maximum dry packing density is used to determine the different contents of the sand dune and fillers (LF and MF). To assure .

Therefore, the trials justify the regional use of this basalt as an aggregate material; its characteristics justify the durability of the brita lavada coating technique, showing a good example of adequacy of an ecoefficient appliion of a local material. Keywords: Madeira island, stone, basalt, characterization, ecoefficiency 1. Introduction
In this paper, the influence of basalt fiber content on some properties of UHPC such as workability, compressive strength, flexural strength, elastic modulus and shrinkage were investigated. The results of this paper show that use of basalt fiber with reasonable content will not affect the workability of the concrete mixture while increasing the flexural strength, compressive strength, and ...
· BOFS is an example of a waste material that has shown potential for use as an aggregate substitute in concrete. The physical properties of slag (Table 2), are highly comparable to those of natural California bearing ratio, compressive strength, and Mohs' scale of hardness value of slag are even reported to be better than that of natural aggregate (Ding et al., 2017).

Black Basalt rock is available in abundance in our area and the main source is scientifically carved Quarry. The natural abundance can fulfil any quantity requirements. Compliance Standards: Super Sand conforms to IS 383 Zone I / Zone II specifiions
UNIT 1 STONES Rocks are aggregates of mineral and are of individual units consisting of crust of the earth Stones is always obtained from rock quarried from quarries is called stones. A stone has to be properly dressed and shaped before it is used at the place of its use. Qualities of a good building stones Strength or crushing strength: For ordinary building works, the strength need not be ...
The effects of aggregate type, size, and content on the behavior of normal and highstrength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and
· When the fibers are distributed in a homogeneous way and used in appropriate quantity inside the concrete, they reduce cracks, contribute to tensile strength, toughness, ductility and durability ...

· Elevating hub heights of offshore WTGs without elevating cost. The new advanced direct drive wind turbine generators require strong winds to turn their large blades. Larger, stronger towers are necessary to reach the higher elevations where the wind blows consistently. Currently, the strength of a large direct drive wind turbine generator (DD ...
