Explanation & Answer

Kindly see attached file with the paraphrased report.I've checked them for matching both in studypool's content checker and plagscan to verify that everything was ok. The maximum match index between the original and final files was of 6%, with all the identified matches corresponding to either the title (I'm not sure if we're allowed to change it) and the references

Abstract
This report analyzes the diverse admixtures that can be presented in the
formulation of concrete samples. In such manner, admixtures are regularly added to
both fresh and hardened concrete to adjust at least one of its structural properties, hence
adapting it for the requirements of each specific application. The report presents an
overview of the current knowledge about the different type of admixtures that can be
used in concrete. Besides, it examines the impacts coming about because of the addition
of these admixtures on the chemical, physical and mechanical properties of the final
concrete product.

Introduction
Admixtures include any compound different from cementitious material, water,
aggregates, and fiber reinforcement used in the preparation of the concrete paste
(ASTM C125 standard). Admixtures must have been incorporated at most during the
mixing process of the concrete paste. Once it...
