| dc.description.abstract | Research has been carried out on construction concrete with the addition of tea leaf pulp. This concrete method uses mixed variations of 0%, 2%, 4% and 6% with the addition of tea leaf pulp as a substitute for part of cement with a soaking time of 28 days. This research was conducted to determine the influence of the physical and mechanical properties of concrete with the addition of tea leaf pulp as a concrete mixture, which was carried out with a composition of materials namely 15.19% cement, 33.04% sand, 43.75 % coarse aggregate and 8.01% water . From the results of the study, a mixture of tea leaf pulp was very influential on the concrete produced. Testing the physical properties of concrete that had been carried out include: density has a value of: 2,510 x 103 - 2,345 x 103 kg/m3, porosity has a value of: 7,34 - 6.36% and water absorption has a value of: 0,323 - 0,278 %. And the mechanical properties include: compressive strength has a value of 23.66 – 13.96 MPa and flexural strength has a value of: 33.3 – 26.6 MPa. From the results obtained testing physical properties and mechanical properties decreased and increased caused by tea leaf dregs that absorb water | en_US |
