The research project, we investigate the behavior of aluminum powder in lightweight concrete for the construction of lightened slabs on their resistance to compression, settlement, absorption, density and time of fragmentation, it is obtained by processes of foamy material and The air lift has a light weight with a density not higher than 1900 kg / m 3 , for the present investigation, aluminum powder was added as it passes from the mesh No. 40 (0.425 mm) to 1.5%, 3%, 4.5 % and 6% of the weight of the cement, without superplasticizer and with 1% superplasticizer, was obtained from the company Química Suiza Industrial EUCO 37. The concrete was designed for 210 kg / cm 2 based on Type ICo cement of the company Pacasmayo, sand and stone of 3/8 "from the" Los Mellizos "quarry in the district of Huanchaco, a constant water / cement ratio of 0.55 and aluminum powder (Al) obtained from the recycling of car pistons is a type of molten aluminum, in the Emp ori or Albarracín, Urb. Palermo, Trujillo. Cylindrical specimens of 10 cm in diameter and 20 cm in height were formed; cured at 28 days in a well with calcium hydroxide (NTP 339.183). To determine its resistance to compression, the NTP 339.034 standard was used for the settlement of NTP 339.035 and NTP 339.187 for absorption and density, for setting time NTP 339.082. With the application of aluminum powder in concrete, but with a higher degree of absorption and in turn maintaining the settlement and its resistance to compression. The standard design or mixture with 0% aluminum powder and without superplasticizer achieved a compressive strength of 224 kg / cm 2 , a 4 "setting, an absorption of 2.22% and a density of 2268 kg / m 3 of the concrete to 1.5% of aluminum powder with superplasticizer based on the tests made for this investigation, presenting a resistance value of 236 kg / cm 2 , settlement of 4 ", absorption of 3.07% and density of 1765.55 kg / m While aluminum powder could be added to 1.5% by weight of the cement without superplasticizer, a resistance of 195 kg / cm 2 , a settlement of 3 ¼ ", an absorption of 4.32% and a density of 1783 kg / m The approximate cost of making a mix for a single floor is S / .250.51 Someone lightweight in any type of structure can see much lighter dead loads, important in areas of high seismic risk The low density of lightweight concrete , assures the concrete structures, during an earthquake the buildings have not become serious, of being in the safest population during the event of a high intensity earthquake.
