| dc.description | In the present investigation the elaboration and analysis of the concrete blocks is shown, using defined amounts of Cal for its later analysis and behavior, the objective of this investigation is to find new technologies or techniques that are not used in our environment for the sector of construction, the main objective is to minimize the negative impact on the environment. The study was carried out by analyzing the mechanical properties of the brick, such as its resistance to compression and properties, comparing this resistance and property with the different bricks described in the work. The properties of the aggregates used in the design of the concrete mix are also compared. These physical properties of the aggregate include volumetric weight, specific gravity, absorption and resistance tests, in each of the tests the trend presented by each of the iterations defined in the study methodology is denoted, the iterations proposed in the substitution Lime partial by cement in the manufacture are 25%, 30%, 35%, 40%, 45%, based on this a comparison is made with the results of the tests of each one of them in comparison to the results of the base block to be compared made entirely of cement. The study was developed according to ACI and ASTM standards. The compressive strength tests were carried out 7 days after the aging of the block. The block with the highest compressive strength after 7 days within the iterations proposed for this investigation was the one with 30% substitution in Cal with 850 [psi], which also had an absorption of 10.93 [lbs/ft3]. | |
