What FCK means?
Acronym. Definition. FCK. Frederico Caldeira Knabben (developer of FCKeditor)
What is meant by FCK and FY?
If fck and fy are characteristic strength of concrete and yield stress of steel respectively and Es is modulus of elasticity of steel, the ultimate flexural strain in concrete can be taken as. 1). 0.002. 2).
What is FCK in steel?
3: Steel Fibers Characteristic compressive strength (fck) = 30Mpa Packing factor = 1.04 Specific gravity of cement (Gc) = 3.12 Specific gravity of fine aggregate (Gfa) = 2.61 Specific gravity of coarse aggregate (Gca) =2.68 Specific gravity of water ( Gw) = 1.0 Bulk density of FA (Wfa) =1594 Kg/m3 Bulk density of CA ( …
How is FCK value calculated?
Face value is the actual value of a digit in a number. To get the place value of a number, we multiply the digit value with its numerical value. For example, in the number 452, the place value of 5 is (5 × 10) = 50, since 5 is in tens place. The face value of a digit is the number itself.
What is the FCK value of concrete?
The characteristic strength of concrete is the compressive strength below, in which not more than 5% of the test results should fall. It is generally represented as fck. But during analysis, we reduce the characteristic strength of concrete and include a factor of safety 0.67. As a result, fck becomes 0.67fck.
Is FCK cube or cylinder strength?
Cube (fck) and cylinder compressive (fcm) strength of reference concrete (0 %) Concrete is a versatile material for civil engineering construction. It has many advantageous properties such as good compressive strength, durability, specific gravity and fire resistance.
Why is 0.67 FCK taken?
In order to overcome the size effect on the concrete, in design, we assume that concrete can carry only 2/3rd of its characteristic strength. Thus we reduce fck to 0.67 fck.
What is FCK and FCM?
Cube (fck) and cylinder compressive (fcm) strength of reference concrete (0 %) Source publication. Cube and cylinder compressive strengths of waste plastic fiber reinforced concrete.
What is FY in concrete?
It is characteristics of compressive strength of Steel used in construction of building and reinforcement designing. the term fy stand for yield strength of steel and term fu stand for ultimate tensile strength of Steel.
What is K in mix design?
K = a statistical coefficient known as tolerance factor or risk factor. The value of K may be adopted from table 20.33. ADVERTISEMENTS: From table 20.33, the value of K is taken as 1.65, putting the value of K is equation (i) we get.
What is the K value in concrete?
The efficiency factor (k-value) is defined as the part of the SCM in an SCM-concrete which can be considered as equivalent to portland cement. In this work, three typical SCM were studied: a silica fume, a low-calcium fly ash and a high-calcium fly ash.
What is K value in concrete mix design?
What is AC in concrete design?
C equals the total compression load. T equals the total tension load. D-X/3 is the moment lever arm for working stress design. D-A/2 is the moment arm for ultimate stress design.
What is N concrete?
The N stands for new billet steel. Until 1984, ASTM A 615, Standard Specification for Deformed and Plain Billet-Steel Bars for Concrete Reinforcement, included two types of billet steel, N and S. Type S steel met more stringent supplementary requirements, which were optional.
