Abstract

This research uses coconut shell ash and glass powder to replace part of the cement aims to find out the compressive strength value of concrete and also the value of water absorption. The use of coconut shell ash as much as 5%, 7% and 9% and glass powder as much as 10% of the weight of cement. And also use additive Sikafume as much as 5% of the weight of concrete. For Normal Concrete, the compressive strength value is 12.39 MPa and the water absorption value is 1%. For the compressive strength value of concrete variation BAS1 with 5% ATK is equal to 11.44 MPa and 1.35% absorption, BAS2 with 7% ATK of 10.32 MPa 1.38% absorption, BAS3 with 9% ATK of 7.50 MPa and 1.38% absorption, BAS4 with 5% ATK with 5% Sikafume of 10.32 MPa and 1.22% absorption, BAS5 with 7% ATK with 5% Sikafume of 10.32 MPa and 1.24% absorption, BAS6 with 9% ATK with 5% Sikafume of 8.82 MPa and 1.37% absorption. The optimal concrete compressive strength value is in the BAS1 variation od 11.44 MPa and the optimal  water absorption is in the BAS4 variation of 1.22%. from the results of tis study, it can be seen that the more coconut shell ash used, the lower the compressive strength of concrete and the more water absorbed. This is because coconut shell ash in fine form reacts with free lime Ca(OH)2 and water into a solid mass that is insoluble in water, namely CSH and CAH.

Abstract

Self Compacting Concrete (SCC) is concrete innovation which  does not  require vibrations during installation and compaction. SCC concrete can flow freely with its weight and is capable of filling a mold well, ensuring perfect compaction without vibration. In 1988, in order to eliminate or reduce the need for vibration to achieve density and thereby reduce the labor required for concrete placement, SCC was developed in Japan. In this research, the production of SCC was investigated by replacing the fine aggregate in the SCC mixture by 3%, 7% and 11% of zeolite material and by adding 0.005% of agave sisalana fiber of cement weight. The 15/30 cm concrete cylinders were used in 16 samples for compressive strength.  It is shown that the values of flowability, filling capacity, and permeability decrease with increasing use of zeolite content based on the results of the research conducted. The results of the compressive strength test show that the variation of 7% zeolite + 0.005% sisalana fiber has the highest value of compressive strength at FAS 0.43, with an average of 38.46 MPa, and the highest value of compressive strength at FAS 0.45, with an average of 37.07 MPa.

Abstract

Cities are one of the main centers for the development of urban areas. The opportunity for investment activities in a city is one of the biggest pull factors for migration. Medan's rapid development can be seen from the construction of many tall buildings such as malls, apartments, and offices. The granting of permits for the construction of these high-rise buildings is closely related to urban spatial planning. Medan City does not yet have a 3D map of the distribution of high-rise buildings, there is only data on the number and location of high-rise buildings. Therefore, urban spatial mapping of high-rise buildings is needed. The model in this research uses a GIS computer model integrated in Arcgis software by taking the object of West Medan sub-district. The results of this study are the suitability of the distribution of tall buildings with a fairly dense uniform pattern in the West Medan sub-district where this sub-district is indeed a service center for trade/business, services and provincial and municipal government activities, and the economy

Abstract

ABSTRACT Sawdust left over from sawmills is a common sight in every wood processing company. So far, sawdust waste processing has not been utilized optimally. Unused saw shavings are usually thrown away or burned while there exist several mankind whosoever disare to use the used sawdust to make tinder. This study shows that using extra materials such as sawdust and sycamore is intended to expansion the compressive strength of the concrete. Such research focus understand the comparison of compressive strength of concrete combined with sawdust and concrete combined with sawdust and sikafume. This research uses sawdust with a difference of 1% and 2% of the load of sand and the reckoning 5% a few load of cement. Cylinder parameters ∅= 15 cm and t = 30 cm. The combination concept applies SNI 7656:2012 steps. Three samples were made for each difference, so there were a total of 18 samples. The test applied is compressive strength of concrete. The maximum compressive strength results in 28 days were achieved in concrete with a combination of 2% sawdust + 5% sikafume, namely 21.81 MPa, experiencing an expansion in the compressive strength value of 9.4% beginning with normal concrete, namely 1.87 MPa, and sawdust concrete experienced The decrease in concrete with a mixture of sawdust + sikafume was 21.6%, namely 4.71 MPa.
