Resumen
El presente trabajo de investigación expone los resultados finales del hormigón
realizado en laboratorio con diferentes tipos de cementos nacionales.
El objetivo de esta tesis es alcanzar las resistencias requeridas de desmolde,
necesarias para los elementos de hormigón prefabricado estructural.
Para lograr este objetivo se han utilizado diferentes dosificaciones, en las cuales se
han variado tanto las cantidades de cemento como la de áridos incluidos en la mezcla.
Además algunas de las dosificaciones incluyen el uso de aditivos superplastificantes con la
finalidad de observar sus influencias en la resistencia a compresión del hormigón
prefabricado estructural, en especial a temprana edad.
Esta tesis también incluye un capítulo acerca de los insertos que el hormigón
prefabricado estructural debe utilizar tanto para izaje como para realizar las uniones entre
paneles. Finalmente se incluye un capitulo acerca de las terminaciones y texturas que
pueden ser realizadas en las superficies de los paneles.
The present research shows the final results of concrete tests performed in the laboratory with different types of national cements. The objective of this thesis is to obtain information about the required resistance to strip forms made as structural precast concrete. To accomplish this objective different proportions of mixtures have been used, thus changing the amounts of cement and aggregate. Besides sorne of the proportions include the use of superplasticizers in order to observe certain influences on the compressive strength of structural precast concrete, especially in its early ages. This thesis also includes one chapter about the inserts that structural precast concrete must use for lifting panels and the ones that are used as joints between the panels. Finally, it includes a chapter about the finishes and textures that can be applied on the surfaces of the panels.
