You are required to prepare a detailed technical report based on the theoretical knowledge and practical. solve it step by step and explain as much as you can. Add references as well.

laboratory experiments conducted. Your report should include commentary based on your

results. Considering the values you have obtained through laboratory experiment, please answer

the following questions;

$-$ Please provide a brief regarding to waste coffee grounds use in cement$-$based

applications.

$-$ What can be thought of the results when comparing the results with control mix?

$-$ Is waste coffee grounds application friendly? Please refer to fresh and hardened

properties.

$-$ Considering the results please provide scientific discussion whether it would be

recommended for practical use. Please cost effectiveness and applicability.Mix Designs
