In the district of San Juan de Lurigancho, the Construction Masters elaborate a concrete whose resistance to compression does not exceed the minimum value of 175 𝑘𝑔/𝑐𝑚2established in the National Building Regulations. This resistance value occurs on site due to the excessive use of water for the sole purpose of obtaining a workable concrete. Consequently, the objective of this study is to obtain a Mix Design with a super plasticizer additive which allows us to obtain workable concretes without the need to alter the water / cement ratio; Furthermore, this Design will be easy to understand for a Site Master who requires a considerable volume of concrete, in this case for a Lightened Slab, whose compressive strength is equal to or slightly higher than 175 𝑘𝑔/𝑐𝑚2. The methodology of this research has been developed, depending on the source of information, through an interview and systematic review with a non-experimental design; for this reason, a survey was carried out with 20 Construction Masters in order to know the compressive strength of the concrete made in situ. Likewise, the systematic review served to find the values of the properties of the materials that are necessary to start the Mix Design by the ACI 211 method. Finally, from the Concrete Mix Design with super plasticizer additive, it was elaborated A Table of dosages whose quantity of materials is expressed, for easy understanding, in lamps; In addition, based on the requirements seen in the Work, a Table was proposed that shows the procedure for the preparation of concrete. This leads to the conclusion that from the use of these Tables the Construction Masters will be able to obtain a resistant concrete based on the Regulations.
