Abstract

This study was conducted to determine the behavior of reduction and compressive strength in claywhich is substituted with sand material and to see the correlation between the value ofconsolidation and the compressive strength on the soil. Because the clay when getting loadingthere will be a significant reduction in soil that affects the reduction in carrying capacity orcompressive strength of the soil. In this study used clay from the village of Belimbing Sari, Jabungdistrict, East Lampung with the coordinates of 105° 39 '10.74 "T and 5 ° 31' 44.26" S.The research was done by testing on samples without a mixture of clay and the clay soil mixedwith sand with varying amounts of sand mixture of 10%, 20%, and 30%. Testing was conducted ona standard compaction test to find the optimum water content, consolidation testing to find thevalue of the coefficient of consolidation (Cv), compression index (Cc) and coefficient ofcompression (Av) and compressive strength testing are free to seek the compressive strength on thesoil.Based on the results of this study can be seen in the behavior of a mixture of clay and sand withoutonce mixed with sand material that is an increase in the value of the coefficient of consolidation(Cv), a decrease in the value of compression index (Cc) and coefficient of compression (Av) and anincrease in the compressive strength (qu) in the clay soil. Value increases and decreases that occurwithout a mixture of clay and after mixed variations mixture of 10%, 20%, and 30% tend to bestable. From this study it can be concluded that the value of consolidation and strong correlationpress substituted clay with sand material that is smaller then the consolidation of soil compressivestrength will be greater as well.Keywords: Soil Clay, Sand, Consolidation, Soil Compressive Strength

Abstract

Organic soils causing many problems for the construction to be built on it, is generally caused bythe physical properties of organic soils that have a very high water content and low carryingcapacity, so that organic soils have less favorable properties for the construction of civil buildings.In this case, there should be a study of compressive strength and shear strength.This research wasconducted in the laboratory by making a sample of the results of a standard compaction, then thesample is done in Optimum condition Dry side of optimum and Wet side of optimum. On the DrySide Of Optimum process, sample was given a reduction of 10% of the optimum water content,while the Wet Side Of Optimum given the addition of 10% of the optimum water content, then thesample is done soaking for 4 days after compaction testing standards.The test results ofcompressive strength and shear strength shows a sample of soil behavior in an Optimumconditions better than the sample in Dry Side Of Optimum conditions and Wet Side Of Optimum.This is due to the pores of the soil Optimum conditions experienced stability and development ofthe soil is very minimum to occurs. Compressive strength and shear strength test is to measurehow strong soil receiving compressive strength and shear strength given to the soil separated fromthe grains.Keywords: Organic Soil, Dry Side Of Optimum, Wet Side Of Optimum, Optimum, CompressiveStrength and Shear Strength

Abstract

Along with the rise of civil construction such as housing or settlements, also increase the demandfor bricks. To be able to meet the needs of these bricks, brick production must be increased. Notonly an increase in production should be done, but the increase in terms of quantity and in termsof quality also needs to be done. One way to do is to add an additional mixture to the compositionof the brickyardIn this study used clay and additional materials TX-300 which has a variety of levels of 0.6 ml, 0.9ml, 1.2 ml and 1.5 ml with the purpose to improving the quality of the bricks, as well as comparingstrong press bricks by modifying the combustion time. Soil samples tested in this study is claywhich derived from Nyunyai street, Rajabasa, Bandar Lampung. Variations of burning time is usedfor one day, two days and three days.After doing research, from the fourth level, the compressive strength maximum average post-combustion bricks are at a level of 1.5 ml with a burning for two days. The compressive strengthvalue of 46.01 kg / cm2. This is due to the greater levels of TX-300, the greater the compressivestrength value, besides the most optimum burning time is for 2 days, this was due to theevaporation of water contained in the most optimum bricks are burning for two days.Keywords: Bricks, Clay, TX-300, Compressive Strenght
