the cone bolt was invented in the 1990s in south africa, aiming to combat rockburst in deep mines (jager, 1992; ortlepp, 1992).the bolt consists of a smooth steel bar and a flattened conical flaring forged at the distal end of the bolt. the original version of the bolt is for cementitious grout (fig. 2.8.1a), and the modified version is for resin grout (fig. 2.8.1b).
the australian code as3600, depending on the area ratio, allows ultimate bearing stress to be increased up to a limit of 1.2 fc'. again, i think the op was asking about bearing, not shear. it is the same reason that you can pass column loads through floors of
design values of concrete material properties according to en1992-1-1 unit weight γ. the unit weight of concrete γ is specified in en1991-1-1 annex a.for plain unreinforced concrete γ = 24 kn/m 3.for concrete with normal percentage of reinforcement or prestressing steel γ = 25 kn/m 3.. characteristic compressive strength f ck. the characteristic compressive strength f ck is the first
member capacity, as precise strength values are given in other design aids. rather, the graphs clearly show stress ranges for which design requirements change. no shear reinforcement (stirrups) are required if vn/(bwd) is less than 1.0√fc’. the capacity vc of concrete in sections reinforced for shear is 2.0bwd√fc’.

- mass flow bin: with a conical discharge and a circular outlet / or with a non conical discharge with a wedged shape outlet - funnel flow bin: with a circular outlet / or rectangular outlet . mass flow bin : all the mass of product will move at the same time. this type
the capacity of concrete is reported in psi – pounds per sq. inch in us units and in mpa – mega pascals in si units.this is usually called as the characteristic compressive strength of concrete fc/ fck. for normal field applications, the concrete strength can vary from 10mpa to 60 mpa.
by considering only shear failure, net ultimate bearing capacity is divided by certain factor of safety will give the net safe bearing capacity. q ns = q nu / f. where f = factor of safety = 3 (usual value) 4. gross safe bearing capacity (q s) when ultimate bearing capacity is divided by factor of safety it will give gross safe bearing capacity
for the need of non-reinforce concrete uses in different types of strengths are required for the structure. when making of walls and footings concrete psi strength, 2,500 is enough could be between, the 4,000 up to 5,000 psi needs for the pavements for construction. free homes for the improvements concrete strength up to 3,500 to the 4,500 psi is enough.

• the load-carrying capacity of a column is affected by the end support conditions. - restraining the ends of a column with a fixed support increases the load-carrying capacity of a column. - allowing translation as well as rotation (i.e. free end) at one end of a column generally reduces its load-carrying capacity.
size reduction (giki) 1. particle size reduction comminution 2. introduction • in the materials processing industry, size reduction or comminution is usually carried out in order to: – increase the surface area because, in most reactions involving solid particles, the rate of reactions is directly proportional to the area of contact with a second phase. – break a material into very small
compressive strength is the capacity of material or structure to resist or withstand under compression. the compressive strength of a material is determined by the ability of the material to resist failure in the form cracks and fissure. in this test, the push force applied on the both faces of concrete specimen and the maximum compression that
the compressive strength of the concrete and concrete testing is must known information in structural design. compressive strength is initially checked by doing mix design to make sure the grade of concrete considered in the structural design is achieved.
