The ratio of cylinder/cube strength depends on the level of strength of concrete and is higher for high strength concrete. However for simplicity IS 516-1964 has suggested this ratio as 0.80. Table 14.1 below shows that this ratio varies from 0.77 to 0.96 in an irregular manner.

A. According to section 184.108.40.206 of ACI 318-19 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used. However, 3- and 7-day test results are not

A solid slab of concrete weighs around 150 pounds per foot for the concrete and 4,50 pounds per square yard. This is for average 3500-4000 psi concrete. If your using stronger or weaker concrete than average then the weight will change. A solid slab of concrete weighs 150 pounds per cubic foot. A cubic foot of broken concrete weighs 75 pounds.
September 1, 2003 CONCRETE MANUAL 5-694.410 (3) Specification 2461.4C2f states that the mixing period begins when the last of the materials enter the mixer drum and ends when the discharg e of the batch begins. Paving m ixers, 0.75 m 3 (1 yd3)
This Readymix concrete product achieves high strength gain and workability that is suitable for all applications where direct discharge from the mixer truck is not possible. Surfacebed Mix This Readymix concrete product achieves high strength-gain, finishing and workability making it suitable for slabs on the ground i.e. factories, shopping centres and parking areas.
The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested after 28 days (fck). In field, compressive strength tests are also conducted at interim duration i.e. after 7 days to verify the anticipated compressive strength expected after 28 days.

Ask an Expert: how much weight is needed to break concrete
2008/1/31. Concrete is extremely strong in compression mode. If a block of concrete is just sitting on the ground and you try to crush it by putting weights on top, it can withstand tremendous forces. This is why we build skyscrapers out of concrete, or partly why. 2. Concrete is much weaker in shear mode. If you take a long, thin slab of concrete
6 Ways to Test Concrete Strength Measurement and 1 You May
2021/6/11These user-friendly sensors are easily installed in the concrete formwork (on the rebar) before pouring to monitor your concrete's in-situ temperature and strength in real-time. The Hub automatically collects this data recorded by the SmartRock sensors and uploads it to the Giatec 360 TM cloud dashboard via LTE where it is synced to your team's mobile devices in
Strength, Water Absorption and Porosity of Concrete Incorporating Natural and Crushed Aggregate
1996/1/1Results also indicate that the natural aggregate concrete has less compressive strength, less porosity and higher water absorption compared to that of concrete made with crushed aggregate. This is true for 0.4, 0.45, 0.5, and 0.55 water cement ratios.
How to Store Chocolate: Tips for Storing Chocolate Keeping it
Store it in a cool, dry place. When chocolate is kept at a consistent temperature below 70F (ideally between 65 and 68F), and at a humidity of less than 55%, the emulsion of cocoa solids and cocoa butter will stay stable for months. But even in a cool, dry place: Remember that cocoa butter (the vegetable fat in chocolate) picks up the smell
