Abstract

Concrete technology innovations need to be made to improve or correct weaknesses and improve the quality standards of the concrete produced. The technology and innovation that has been developed is lightweight concrete. This research aims to find lightweight but high compressive strength concrete (optimal concrete) at K200 concrete grade. With mixed materials for concrete in the form of foam agent, superplasticizer, and fly ash, the tolerance limit for mixing materials at the age of 14 days and 21 days of concrete with experimental methods with cube-shaped samples. Based on the purpose of this study, namely looking for lightweight concrete but high compressive strength (optimal concrete) in this study the average foam 15%, superplasticizer 1.5, fly ash 10% age 14 days with an average of 254.74 kg / cm² and average foam 15% superplasticizer 1.5%, fly ash 10% age 21 days average compressive strength 225.87 kg / cm².

Abstract

The soil condition in Sigar Bencah, Semarang City, has characteristics that are less supportive of construction, such as cracks, low bearing capacity, and instability. This study aims to evaluate the effects of soil stabilization using lime and cement on soil compaction and unconfined compressive strength (UCS). The variations of lime and cement content used are 0%, 5%, 10%, and 15%, with lime and cement ratios of 30:70, 50:50, and 70:30. The tests conducted include physical property analysis, standard compaction, and UCS testing. The results of the study show a significant improvement in both UCS and optimal soil compaction after stabilization treatment. The optimal additive combination for improving soil quality was found at a 10% additive content with a 50:50 lime-to-cement ratio, which produced a UCS value of 14.2 kg/cm². This indicates that the use of lime and cement as stabilization materials can enhance soil strength and stability, making it suitable for use in construction in areas with poor soil conditions. This stabilization can also serve as a solution to increase soil bearing capacity, reduce potential damage, and improve soil performance in various construction applications.
