Abstract

This research aimed to determine weight-volume, compressive strength, and split tensile strength of concrete due to the use of plastic pellets (polypropylene) as a coarse aggregate and stone ash as a partial/a whole replacement sand needs to utilize plastic waste and stone ash which is a waste of stone-crushing machine. The test specimen was made of a mixture of cement, sand, coarse aggregate of plastic pellets and water. The design of concrete mix by Indonesian National Standard (SNI) with normal concrete compressive strength of 10 MPa was planned. Variations of the specimen lied on the mixture of stone ash and sand, respectively for 0% and 100%, 25% and 75%, 50% and 50%, 75% and 25%, and 100% and 0%. The object of the research was a cylinder diameter of 100 mm and height of 200 mm for testing of weight-volume and compressive strength, and a cylinder diameter of 150 mm and height of 300 mm for testing of split tensile strength. The results of the research showed that the higher level volume of stone ash in concrete, the higher weight-volume and compressive strength. It was increased in split tensile strength of the concrete levels of 0% to 50% stone ash, and it was decreased in levels of 75% and 100% stone ash. The results of weight-volume testing showed that all variations of concrete were classified as lightweight concrete because it had weight-volume of less than 1850 kg/m3 (Balitbang Kimpraswil, 2003b). Neville and Brooks (1987) also classified the concrete as lightweight concrete because it had weight-volume evenly less than 1800 kg/m3 and 1900 kg/m3. The results of compressive strength testing showed that concrete with stone ash content 0-75% were classified as very lightweight structure because it had compressive strength of less than 6.89 MPa, while levels of 100% were categorized as very lightweight structure with compressive strength from 6.89 to 17.24 MPa (Balitbang Kimpraswil, 2003b). According to Neville and Brooks (1987), concrete with stone ash content 0-75% were classified as lightweight concrete for heat resistant (compressive strength of 0.7 to 7 MPa), while levels of 100% were categorized as lightweight concrete for masonry (compressive strength of 7-14 MPa).Keywords: Polypropylene (PP), stone ash, compressive strength, split tensile strength, lightweight concrete

Abstract

In the recent decade , the development of retaining wall construction keeps growing rapidly along the optimization of the use of available land. The main purpose of this construction is restrain the land so as not landslide Due to the load that it work in addition to the utilization of the space available. In this case study in sindu kusuma edupark project using construction type anchoring ground gravity wall. If the structure of gravity wall is not safe withstand the force that worked , then required alternative design construction of retaining wall of another appropriate. Construction retaining wall that can be used as alternatives is sheet-pile wall or commonly called Turap. The difference of gravity wall and turap lies in the stability analysis of construction and materials. Excess of sheet pile of this wall is the tough a lighter , the implementation of the gravity relatively quickly than wall, Suitable used for the drift the ground with a height was , the quality of construction uniform and more secured construction than manual for using prefabricated construction. From the analysis of stability gravity wall , we can conclude that when the structure receives of static load, Construction stability was not secure against overtuning , sliding , axial load , and broken foot structure but it still safe receives sliding and capacity stability fulfilled. When encumbered by dynamic loads, structure safe against bolsters, sliding, and soil bearing capacity.The Sheet pile wall selected as a substitute for wall gravity is prefabricated concrete Wika Beton , with type w-325 a 1000 - length: 8 m with a long as deep as 3 m of installing. The type of sheet pile used anchorage sheet pile of continuous type, with 10 mm in diameter and the distance is 3m.
