Correct Ratios for Concrete Mixes
I do have tables for trial concrete mixes but they only go up to 40 MPa. According to Fulton’s Concrete Technology published by the CCI, which has a chapter on concrete mix design (maybe there’s a copy in your school library?), high-performance concrete with a 28-day compressive strength of 68,9 MPa = high strength concrete.
The Environmental Impact of Asphalt Plants
The majority of emissions at asphalt mixing facilities come from the combustion of fuel, such as natural gas, that are used to dry and heat the rock or aggregate and to keep the temperature of the asphalt hot. Most of the other potential emissions, such as the dust gener - The Environmental Impact of Asphalt Plants

Buildings - Concrete Testing Requirements
Concrete Testing Requirements . Applicants cannot identify responsibility or certify completion for the concrete inspection and design mix items on the TR1.Applicants must complete two Technical Reports (TR2 and TR3 Forms) to identify information about the testing labs, the strength and mix of the concrete being used.
Some common examples are commercial properties, industrial plants, mills, manufacturing plants, multi-unit offices or residential buildings, schools, hospitals and municipal facilities. Asset owners have unique responsibilities throughout the equipment life cycle that are aimed at improving safety and lengthening equipment life.

A Simple Guide to Concrete Cube Testing
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.
Concrete grinding, Practice of grinding, Health and safety
Concrete grinding produces silica dust. If the dust is breathed in over a period of time, it can lead to a disease called silicosis or scarring of the lungs. This was such a common problem for grinder operators in years past that one of its common names was 'grinder's asthma'.
