The present investigation entitled "Evaluation of the influence of the effects of the addition of expired cement in different percentages, on the index-physical and mechanical properties of the clayey soil of the subgrade of Chacapunco Street in the District of Chinchero, 2023", was born from the need to reuse the expired cement that normally has to be discarded and, hand in hand, to improve the properties of the clayey soil. Clay soils generally do not have an adequate quality to form a subgrade, so they must be improved with some technique. Therefore, the influence of expired Portland cement on the stabilization of a clayey soil was evaluated. A soil study was carried out to identify its index-physical and mechanical properties. Type IP Portland cement with an expiration time of 5 months was used as a stabilizing additive in percentages of 4, 7 and 10% of the dry weight of the soil sample. Moisture content, granulometric analysis, liquid limit, plastic limit, contraction limit, modified proctor, CBR and unconfined compression tests were carried out, through which the influence of expired Type IP Portland cement on its plasticity index, degree of contraction was evaluated. , CBR index, % expansion, resistance to unconfined compression and finally determine the number of bags of expired cement required for 1m3. For this purpose, we have used a quasi-experimental methodological design which is developed with non-random experimental groups, has a quantitative approach, since it is based on data collection to test hypotheses, based on numerical measurement and analysis. Statistical, it presents a descriptive-correlational level because it will be determined through tests, a correlation because there is a relationship between the variables and the method used is the hypothetical deductive one, because first the observation was made, then the hypothesis was raised , subjecting it to scientific tests to finally validate or deny it. The clayey soil analyzed was classified as CL according to SUCS. With the addition of 10% cement, its plasticity index was reduced from 15.07% to 5.69%, its degree of contraction was reduced from 31.92% to 10.6%, its CBR index increased from 1.44º/o to 127.18% to 95% DSM. , its % expansion at 55 blows was reduced from 0.9% to 0.08% and the unconfined compressive strength increased from 3.85 kg/cm2 to 5.06 kg/cm2 and the necessary number of bags of expired cement required for 1 m3 of subgrade with a thickness of 0.15 cm for 4.7 and 10% is 2.3 and 4 respectively.
