Concretes consisting of portland cement (OPC), silica sand, gravel, water, and recycled PET particles were developed. Specimens without PET particles were prepared for comparison. Curing times, PET particle sizes, and aggregate concentrations were varied. The compressive strength, compressive strain at yield point, and Young modulus were determined. Morphological and chemical compositions of recycled PET particles were seen in a scanning electron microscopy. Results show that smaller PET particle sizes in lower concentrations generate improvements on compressive strength and strain, and Young’s modulus decreases when the size of PET particles used was increased.

BIOLOGÍA Y QUÍMICA
The development of the packaging industry has promoted indiscriminately the use of disposable packing as Tetra Pak, which after a very short useful life turns into garbage, helping to spoil the environment. One of the known processes that can be used for achievement of the compatibility between waste materials and the environment is the gamma radiation, which had proved to be a good tool for modi cation of physicochemical properties of materials. The aim of this work is to study the e ects of waste cellulose fromTetra Pak packing and gammaradiation on themechanical properties of cement concrete.Concrete specimens were elaborated with waste cellulose at concentrations of 3, 5, and 7 wt% and irradiated at 200 , 250 , and 300 kGy of gamma dose. The results show highest improvement on the mechanical properties for concrete with 3 wt% of waste cellulose and irradiated at 300 kGy; such improvements were related with the surface morphology of fracture zones of cement concrete observed by SEM microscopy.

CIENCIAS SOCIALES
In the present paper, the 1985 mexico earthquake and its influence in the research activity in the country are analyzed. The discussion is focused in the masonry and concrete structures, the main research results and its applications in the construction specifications a commented, also it is presented the evolution of construction code in mexico related to the main earthquake events in the country. Finally the application of the actual code recommendations and specifications in the construction practice are presented, remarking the most commons deficiencies and mistakes in the actual practice, in this part the differences between formal and non formal construction are compared
