Abstract

Nowadays, a construction uses a lot of concrete with highly strong power that is needed to support materials supporting the construction. With the improvement of concrete technology nowadays it is possible that high quality concrete with the suppression of greater than 70 MPa. Aceh Province, which is located, at the most tip of Sumatera Island has a great number of natural resources and materials that can be used in order to make concrete. These available resources are used for making high quality concrete with the pressure of 70 MPa. This research is going to explore the characteristic of concrete mechanic comprises of the strength of its pressure, the strength of its tight pressure, the bow strength and the sliding strength that can be reached by using additional material of palm nutshell as an additife replacement as apart of concrete use and the variation of the variety of superplasticizer optimum percentage of Sikament LN, Sikament NN and Viscocrete-10 by rude aggregation with maximum measure is12 mm. its concrete is used as Portland concrete type I with vary kinds of superplasticizer by each maximum percentage of Sikament LN is 1%, Sikament NN 1,5% and Viscocrete-10 1,5 % . the factor of water concrete is 0,3 and the amount of palm nutshell dust as an aditif that is used is 10%. The value of pressure and tight breaking strenght, flexibility tight strengh and sliding strenght from third variaties of superplasticizer, namely Viscocrete-10 with the percentage is 1,5% having bigger valuecompred to Sikament NN 1,5% and Sikament LN 1,0%. In terms of testing hot hydration the result shows that the viscocrete – 10 has been able earlier to prevent hot hydration with value is 6 hour; 24oC compared to Sikament NN 8 hour; 240C and the kind of Sikament LN 78 hour; 250C.

Abstract

In 2002, through the national standardization agency, the Indonesian government issued SNI 03-1726-2002 on Earthquake Resilience Planning Standard for Building Structure to anticipate the effects of earthquake on building. However, after the standard has been issued there have been several other major earthquakes that rendered it necessary to revise the existing standards. Therefore, in 2012 the government issued SNI 03-1726-2012 on Procedures for Earthquake Resistance Planning for Building and Non Building Structures. When viewed from both these standards, it can be seen that Aceh province is one of the provinces with high earthquake intensity so it is necessary to do a research to observe the effect of changes of both standards to the ratio of column capacity and minimum reinforcement requirements for buildings constructed in Aceh province. Based on the results of the research, the average column capacity ratio against the load in SNI 03-1726-2012 has increased by 45.02% and the average minimum reinforcement requirement available is only 54.5%. The increase is due to an increase in primacy factor from 1.0 to 1.5, causing increased structural load. In addition, there was an increase in the combined burden in the form of 30% additional redundant factors as well as the addition of earthquake load due to an increase in rock bed acceleration factors in some regencies. Thus it can be concluded that the building under review has not fulfilled the requirements of SNI 03-1726-2012 and is recommended for planning by adding a shear wall to reduce the structural load.
