This research contemplates the development of an optimal design of self-consolidating concrete (SCC) with cement added pozzolanic for the columns of residential buildings in the city of Puno. Through an experimental plan of 10 concrete mix designs, with 3 different cements, which are: IP up to 40% pozzolan, IPM up to 15% pozzolan and type I. A TM140 superplasticizer additive and a SikaCem accelerator additive. The coarse aggregate used has a TMN of ½” and complies with the granulometry of Spindle 7. The fine aggregate has a fineness modulus of 2.90. These designs were evaluated through tests in fresh concrete, such as temperature, air content, unit weight, T50 flow extensibility, J ring and L box. 7, 14 and 28 days. In addition, for the mix designs with the best optimization percentage, the plastic contraction test was used to measure which one presented the least crack. The M-05 design with the IP cement type was the best mix with the best performance, with a loss of extensibility of 50 mm for a range of 2 hours, with a compressive strength of 312 kg/ cm2 at 28 days. and in the plastic contraction there was no crack compared to the mixtures with type I cement that had 0.6 mm and IPM with 0.2 mm. In the cost-benefit analysis, it was found that the mixture with IP-type cement represents a 4.99% additional cost compared to the conventional one. However, they have a tendency to behave better against cracks, which makes them a good alternative for the columns of residential buildings in the city of Puno.
