Abstract

In the development of increasingly developed technology and the demands of the community's needs for infrastructure facilities, it also affects the development of a construction field. This is also no exception in the manufacture of mortar which is used as a non-structural material in buildings. In making mortar itself, it is also influenced by developing technological developments, one of the types affected is pozzolan mortar. Pozzolan mortar has added materials derived from nature or industrial waste. In Indonesia, waste from eggshells is increasing every year, because eggshells are one of the people's favorite food ingredients. The eggshells have contain calcium carbonate (CaCO3) compound which is an element than cement. The materials of making the mortar itself are water, cement, and sand. This research aims to utilize egg shell waste as an added material in mortar with variations in the percentage of 0%, 5%, 10%, and 15% eggshell powder. From the results obtained, the addition of eggshell powder at maximum compressive strength lies at a percentage of 15% of 300 MPa.

Abstract

Mortar is a mixture of materials composed of fine aggregate (sand), adhesives such as (clay, lime, portlaand cement) and water with a certain composition. Mortar can be affected by several specification factors such as density, mortar age, type of bonding material, and aggregate properties. In this study using coconut fiber ash as an added material in making mortar which has a function as an enhancer of compressive strength value in mortar. In coconut fiber ash, it has an important chemical compound for mortar, namely silica compounds which function as the main element to increase the compressive strength value of mortar. The purpose of the study was to determine the effect of adding coconut fiber ash material on the compressive strength of mortar with a percentage of 0%, 2.5%, 5%, 7.5%, 10%. From the results of the research conducted, a compressive strength value of 253 Mpa was obtained at a percentage of 10% of 7 days old and 253 Mpa at a percentage of 2.5% of 7 days old.

Abstract

Concrete is a material that is commonly used when doing construction work today. Because concrete has several advantages when compared to other materials, such as being easy to form, resistant to weather changes, has high compressive strength, and is durable. In this study the use of Silica Fume as an additive to flow concrete has the function of improving the quality of flowing concrete. Silica Fume has an important role in affecting the chemical and mechanical properties of concrete. Judging from its chemical properties, Silica Fume geometrically fills the voids between cement materials, and causes the pore diameter to decrease and the total pore volume to decrease. Meanwhile, from its mechanical properties, Silica Fume has a pozzolanic reaction (a material containing silica/silica dioxide and alumina compounds) which reacts to the limestone released by the cement. The aim of the research is to increase the maximum compressive strength of flowing concrete by using Silica Fume added with varying percentages of 0%, 5%, 6%, 7.5%, 9%, 10.5% and 12% and using a superplasticizer of 1.5 %. From the results of the research conducted, it was found that flowing concrete with added silica fume on concrete compressive strength was able to reach 7.5% at 7 days of age of 25.91 MPa and at 28 days of concrete age was obtained at 26.19 MPa.
