The hollow block sizes in the Philippines are the following:40cm (length) X 20 cm (width) X 4 in (thickness)40cm (length) X 20 cm (width) X 5 in (thickness)40cm (length) X 20 cm (width) X 6 in (thickness)
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.

A typical mixture of concrete will be 10 to 15% cement, 60 to 75% aggregate, and 15 to 20% water.
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
For M25 grade concrete the seven days crushing for site condition shall be not less than 67 % of M25, i.e not less than 16.75 N/mm2 But for target strength of M25 for mix design taken i.e for M25 it is 32 and the 7 days strength shall not be less than 22 N/mm2
Nothing. Concrete doesn't come in gallons for measuring. Milk is in gallons.
100 cubic meters.
Digit 30 stands for minimum strength required after 28 days and 20 stands for maximum size of aggregate
That is an area measurement, whereas concrete is measured in volume, typically cubic yards in the US. The costs vary widely based on local availiblity of materials and the type of concrete mix. The national average is about $100 for a cubic yard of concrete.
The amount of rebar in a cubic meter of concrete can vary depending on the design specifications of the concrete structure. Typically, rebar makes up around 1-2% of the total volume of concrete, so in a cubic meter of concrete, there may be around 20-40 kilograms of rebar.
depending upon the type of concrete and the mix rate, a gallon of concrete weighs anywhere from 17-20 lbs. So 85 to 100lbs plus the weight of the bucket.
