What does C35 45 concrete mean?
Context 1. foundation was cast on site, mostly from C35/45 concrete (i.e., concrete designed to have a 28-day cube strength of 35-45 MPa).
What does rc28 35 concrete mean?
RC 28/35 is a reinforced concrete mix that is best suited to moderately exposed conditions – specifically floors for farm buildings such as barns and livestock housing. RC 28/35 concrete can also be used in industrial floors for more general use.
What is normal density concrete?
around 150 lbs/cu ft
Typical concrete density is around 150 lbs/cu ft. Lightweight concrete can weigh as little as 95 lbs/cu ft. High-density concretes range from 190 to 260 lbs/cu ft.
What strength is C35 concrete?
35 newtons
With a strength rating of 35 newtons after 28 days, C35 / PAV2 concrete is most commonly used when building heavy-duty pavements and external slabs. This designation of concrete is similar to PAV1 mixes (also designated as C30 / ST 3), but is much stronger and more suitable for heavy duty applications.
What is the mix ratio for C35 concrete?
0.55
The C35 mix has a water-cement ratio of 0.55, and a cubic metre might comprise of 950kg of stones, 900kg of sharp sand, 200kg of blended cement, 110l of water (which is actually less by volume than in the waterproof concrete) and a small amount of WRA.
What is the ratio of M35 grade concrete?
Different types of concrete grades and their uses
| Concrete Grade | Mix Ratio (cement : sand : aggregates) | Compressive Strength |
|---|---|---|
| Standard Grade of Concrete | ||
| M25 | 1 : 1 : 2 | 3625 psi |
| M30 | Design Mix | 4350 psi |
| M35 | Design Mix | 5075 psi |
What does C40 50 concrete mean?
C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the method of testing using concrete cubes, the tested compressive strength should be compared to the second number.
What does C32 40 concrete mean?
C32/40. C32/40 is a strong commercial grade concrete. It can be used where high structural strength and support is required and when large heavy weights will be applied in small areas (e.g. farm traffic). Ideal for: HGV parks, agricultural yards, septic tank foundations, structural beams and hydro dam applications.
What is high density concrete used for?
High density concrete (HDC) consists of concrete with a density higher than normal 2300 to 2550 kg/m³ and is used for special purposes such as radiation shielding, counter weights, ballasts, safe walls and safe roofs.
What is density concrete?
The density of concrete is a measurement of concrete’s solidity. The process of mixing concrete can be modified to form a higher or lower density of concrete end product. A very high density of concrete is that made around steel cables that have been stretched by hydraulic jacks.
What is C35 concrete used for?
GRADE: C35 CONCRETE It is commonly used for structural piling and creating external slabs and walls. Other uses include commercial slabs including metal reinforcement and agricultural and construction industry containment areas such as yards and barns.
What is RC35 concrete?
RC 35/45 is a very strong, reinforced concrete mix that is best suited to highly demanding exposed conditions such as farm buildings and outhouses. Due to its excellent strength and durability RC35/45 concrete can also be used for industrial reinforced concrete floors.
What does C35 / C45 concrete mean in concrete?
C35 and C45 represents the compressive strength of concrete. C 35 means it is the compressive strength of concrete is 35 MPa (N/mm2). The compressive strength of concre is tested by casting 15x15x15 cm concrete cube and curing it for 28 days and then crushing it in machine to get the compressive strength of the concrete.
What does C35 mean on a construction drawing?
In the UK, reference to a C35 concrete on a construction drawing usually means a concrete designed for that Contract to withstand a compressive load of 35Newtons/square millimetre. (45 N/mm2 for C45) Details of the C35 mix design will be included in the contract specification document.
How is the bulk density of concrete determined?
Density is an important parameter for concrete. The bulk density or unit weight of concrete is the mass or weight of the concrete that required to fill a container of a specified unit volume. Unit in kg/m 3 or lb/ft 3. lb/ft 3 is also used as pcf.
How is the compressive strength of C30 / 37 concrete related?
The characteristic compressive cube strength fck,cube is the second value in the concrete class designation, e.g. 37 MPa for C30/37 concrete. The value corresponds to the characteristic (5% fractile) cube strength according to EN 206-1. The mean compressive strength fcm is related to the characteristic compressive strength fck as follows:
