The influence of incorporating expanded clay in the mix design and strength of high-performance lightweight concrete in the District of Lircay - Angaraes - Huancavelica, to this effect, the question of our research is the following: How does the incorporation of clay influence expanded in the resistance of high-performance lightweight concrete in the District of Lircay - Angaraes - Huancavelica?, The influence of incorporating expanded clay in percentages of 5%, 10%, 15% and 20%, in the mix design significantly influences the resistance of high-performance lightweight concrete, workability and homogeneity are maintained as the clay is increased. expanded obtaining a settlement of 6 to 2.5 cm. within the limits of a balanced consistency. From the results obtained at 28 days of age of f'c=210 kg/cm² and f'c=280 kg/cm², it is concluded that the concretes with the addition of Clay in their...
