摘　　要：The residues generated by big industries are directly and gradually impacting the environment,and some of these have not been fully tapped in a proper destiny.Therefore,some researches and studies about minimalizing the residue’s disposal become viable.The biodiesel industries have been producing increasingly glycerin as the main residue.Based on that,it is considered as a good option of the reutilization of this material,for example,the merging at the concrete’s production.Considering this argument,the addition’s effects of glycerin were evaluated as well as the influence of its adding at the compressive strength.The proof-bodies were formulated according to the trace in proportion of 1:1:2(cement,sand and gravel,respectively)and 0.4 L of glycerin added at the final trace.On the bases of the survey results,it was verified that the proof-bodies without the addition of glycerin presented average mechanical resistance of 12.2±1.95 MPa after twenty eight(28)days of curing,and mechanical resistance of the proof-bodies with the addition achieved resistance of 26.2±1.62 MPa,suggesting influence on the hydration kinetics of the concrete.
