Abstract

The increasing development of construction technology in Indonesia has resulted in a variety of new innovations in its application. In concrete, for example, there have been many modifications and substitutions in the constituent materials. In the case study, cohesion soil can be applied as a mixed material with mortar-foam. This material is a local material which, when mixed with foam, will expand to four times the initial volume so that the material required is not much and the procurement of embankment material does not need to be imported from other locations. Another advantage of this method is that the weight and strength values can be planned according to needs. Foam mortar is a cement-based mixture with water, foam and fine aggregate. This mixture is called mortar because there is no coarse aggregate used in it. Foam is produced by mixing water with a foam agent derived from vegetable protein using a foam generator.Keywords: foam mortar technology

Abstract

Technological advances and the economic crisis that occurred in Indonesia, directed infrastructure development towards the use of Structures with lightweight materials. But overall it does not have an impact on increasing the Strength of the Structure. The use of lightweight materials as a structural material will reduce the total weight of a building, thereby reducing the supporting parts and foundations. Concrete is a material commonly used for Structures. This is because Concrete has many advantages when compared to other building materials. However, concrete has one weakness, namely its density is quite high so that the dead load on a structure becomes large. Based on SNI (03-2847-2002), concrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate, and water with or without additives to form a solid mass. There are various types of additives used in concrete mixtures, namely steel. Polymer (polyoropylene), glass, and carbon..Keywords: Geogrid concrete compressive strength
