Abstract

The aggressive environment can damage concrete especially sulfate attack which would decrease compressive strength of concrete and also cause corrosion. Therefore, the additive was added into concrete mixture. A glass powder is an additive that contains binding substance in reaction with water and accelerate concrete hardening.This final project will discuss the effect of glass powder as replacement of cement in concrete mixture to concrete compressive strength that soaked in water and water containing sulfate. In this research, concrete sample is cylindrical with diameter of 15 cm and heigth of 30 cm which consisting of normal concrete, 5%, 10%, 15% and 20% glass powder in concrete mixture with w/c 0,4 and 0,5. Soaking is done in two ways, ie soaked in water and water containing sulfate. The concrete compressive strength test was performed at 7,21 and 28 days. The result of this research, the concrete that soaked in water and water containing sulfate has the highest compressive strength on 5% glass powder with w/c 0.4 of 44,92 MPa and 43,78 MPa on 28 days and 5% glass powder with w/c 0,5 of 35,86 MPa and 34,54 MPa on 28 days. Besides of that, the attack of sulfate can decrease compressive strength of concrete which have been soaked in water containing sulfate. The smallest reduction of compressive strength occured on 20% glass powder with w/c 0,4 of 1,70% on 28 days and 20% glass powder with w/c 0,5 of 2,99% on 28 days. It can be concluded, despite the large increase glass powder in concrete mixture can decrease concrete compressive strength, but the effect of sulfate to concrete compressive strength is getting smaller.   Keywords: glass powder, sulfate, compressive strength

Abstract

In order to minimize the damage of concrete structures due to external influences , especially due to sulfate attack that occured naturally in soil and groundwater where the structure is located, and to utilize glass wastes in big cities, a proportion of sand was replaced by glass powder. Two different mix design is calculated based on ACI method (w/c 0.60 and 0.65 ) , with 0%,5%, 10%, 15% and 20% passed a #8 sieve glass powder replacements investigated. Concrete soaked for 7 , 21 and 28 days with 2 types of water were plain water and a 5% sulfate solution . The test results showed that compared to normal concrete for both mix designs, the slump of 20% glass sand replacement concrete was the smallest than the other. Compressive strength of concrete with glass powder substitution is higher than the design compressive strength, and continues to increase with the addition of glass powder content. At 28 days, the compressive strength of specimens with various amount of glass sand replacement were all higher than that of the design strength when soaked in sulfate solution.

Abstract

The Concrete buildings which located in certain location susceptible to sulfate attack. The sulfate can damage the buildings, one of the alternative that can be used to improve the durability of concrete due to sulfate attack by reducing the porosity, the glass powder as a sample that can be use. The glass powder has a pozolanic character that can fill the empty voids in the concrete. The purpose of this study was to determine the effect of glass powder as fine aggregate replacement in concrete that exposed and not exposed to sulfate attack. In this research, some tests were done to determine the compressive strength by replacing sand with 0%, 5%, 10%, 15% and 20% of glass powder. The cylinder specimen was soaked with plain water and  5% MgSO4 solution with 7, 21 and 28 days, using water-cement ratio 0,4 and 0,5. The  result shows that the smallest percentage reduction in the compressive strength due to sulfate attack was founded in 20% of glass content, for w/c = 0,4 in 7 days was 0,57% and for w/c = 0,5 was 1,45%., The highest compressive strength of concrete that was soaked with plain water and 5% MgSO4 solution was founded in 20% of glass content, for w/c = 0,4 in 28 days was 44,72 MPa and 43,85 MPa and then for w/c = 0,5 was 37,80 MPa and 36,45 MPa. So if the content of glass increase the compressive strength will increase and the percentage reduction in compressive strength due to sulfate attack will decrease.   Keywords: glass powder, compressive strength, sulfate.

Abstract

In the concrete’s buildings with large spans , the using of the ordinary structure system will create  the dimensions of the beam , column , and plate are large so that the building be disproportionate . Therefore, the waffle slab structure system was developed . Waffle slab is crossed beam system that is used to increase the stiffness of the plate , so that the smaller the deflection occurs , thus dimensional of structural elements can be minimized and eventually become less material usage . Waffle slab has many types , including the type of parallel waffle slab and diagonal waffle slab. This research aims to determine which system is more economical and rigid between the two types of those . This research uses 1 ordinary building model as a standard , 5 parallel waffle slab’s building and 5 diagonal waffle slab’s building with Lx and Ly spans is 10 m , height of each floor is 4 m , and given the same loads in accordance with the regulations of the American Society of Civil Engineers ( ASCE ) . There are 5 combinations of crossed beams who start of division 1 Lx and 1 Ly to division 5 Lx and 5 Ly for each waffle slab building model  .

Abstract

Indonesia is an earthquake prone areas, to reduce the risk of the disaster required the construction of earthquake resistant buildings. The structure usually design base on the elastic analysis that would be multiplied by load factor to simulate the ultimate condition. Actually, the behavior of building subject to seismic loads are in-elastic. Concrete structure is the most commonly material in the construction. In high-rise buildings quake resistant, generally the forces at column is enough to resist the quake loads so need to use rigid structural elements such as shearwall to resist combined shear force, moment and axial force due to earthquake. With using shearwall, the majority of quake loads will be absorbed by shearwall.  This essay took the topic about Sriwijaya University dorm building with lateral resistant combined moment resisting frame system and shearwall. Building were designed according to SNI 03-2847-2002 and SNI 03-1726-2002. From the result of the calculation have been done, the result is dimension and rebar reinforcement of the struktural elements. Beam dimension 25 x 40 cm, column dimension 40 x 40 cm, slab thickness 16 cm and shearwall thickness 25 cm. Joint displacement deviation due to x axis quake load and y axis quake load is 5,52 mm and 5,71 mm, where that result not exceed service limit and ultimate limit of building.   Key Words : earthquake, concrete, lateral resistant, mrfs, shearwall

Abstract

One of the area in Palembang City that often floods is 9/10 ulu residential on sub DAS Aur. Existing drainage channels have dimensions that are not sufficient to flow peak dischange caused by storm and tides. Therefore, it is necessary to study the drainage channels in the residential areas. The first stage in the analysis begins with hydrologic analysis to calculate the distribution of rainfall using maximum daily rainfall data for 20 years from 1993 to 2012. The next step calculates the design rainfall intensity, then calculate the design rainfall hyetograph using ABM method (Alternating Block Method). By using SWMM 5.0 (Storm Water Management Model 5.0) program can analyze the available drainage system in the residence, then the input data was complete. Floods simulation about the improper water drainage can be achieved after inputting the data. Redesigning the rational method and simulated by SWMM 5.0 program to replace the previous channel dimensions and dimensional data input channels planned, then the simulation results with good water flow in the channel was ideal.Key Words: Drainage system, flood, rational method, SWMM 5.0
