Hello Reski!
Allow me to give you some suggestion.
1. Misspellings


Right spelling-> concrete

2. Subject verb agreement
percentages of material which are used to produce

3. Passive voice
see the materials that is used, which are limestone...

Hope it helps you :)

Hi, I want to make some comments

1. ... information about how to steps and equipment are used to ...
You need verb auxiliary before 'used' because you want to make passive sentence

2. ... the cement-making process,and there are some percentages ...
You can use conjunction 'and' rather than 'comma' to give another idea

3. The steps of cement production areis lime stone and ...
You only mention want step in that sentence. So you should use 'is' instead of 'are'

Thank you
Keep writing
