The Mechanical Properties of Brick Containing Recycled Concrete Aggregate and Polyethylene Terephthalate Waste As Sand Replacement
E3S Web of Conferences 34, 01001 (2018) https://doi.org/10.1051/e3sconf/20183401001 CENVIRON 2017 The mechanical properties of brick containing recycled concrete aggregate and polyethylene terephthalate waste as sand replacement Faisal Sheikh Khalid1*, Nurul Bazilah Azmi1, Puteri Natasya Mazenan1, Shahiron Shahidan1, and Noorwirdawati Ali1 1Jamilus Research Centre for Sustainable Construction (JRC), Faculty of Civil and Environmental Engineering, Universiti Tun Hussein Onn Malaysia, Johor, Malaysia Abstract. This research focuses on the performance of composite sand cement brick containing recycle concrete aggregate and waste polyethylene terephthalate. This study aims to determine the mechanical properties such as compressive strength and water absorption of composite brick containing recycled concrete aggregate (RCA) and polyethylene terephthalate (PET) waste. The bricks specimens were prepared by using 100% natural sand, they were then replaced by RCA at 25%, 50% and 75% with proportions of PET consists of 0.5%, 1.0% and 1.5% by weight of natural sand. Based on the results of compressive strength, only RCA 25% with 0.5% PET achieve lower strength than normal bricks while others showed a high strength. However, all design mix reaches strength more than 7N/mm2 as expected. Besides that, the most favorable mix design that achieves high compressive strength is 75% of RCA with 0.5% PET. 1 Introduction Cement and sand bricks are a type of bricks that is commonly used in low and medium cost housing development and other commercial constructions in Malaysia since it is easy to produce and cheap [1]. However, there is an issue in producing these materials especially in developing areas where manufactures find it difficult to locate adequate sources of natural cement and aggregate supply [2-3]. -

Tysi ˛acleciaPa´nstwa Polskiego 7, 25-314 Kielce, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-41-34-24-571 Abstract: Wastewater treatment processes produce sewage sludge (SS), which, in line with environ- mental sustainability principles, can be a valuable source of matter in the production of lightweight expanded clay aggregate (LECA). The literature on the influence of SS content and sintering tempera- ture on the properties of LECA is scarce. This paper aims to statistically evaluate the effects of SS content and sintering temperature on LECA physical properties. Total porosity, pore volume, and apparent density were determined with the use of a density analyzer. A helium pycnometer was uti- lized to determine the specific density. Closed porosity was calculated. The test results demonstrated a statistically significant influence of the SS content on the specific density and water absorption of LECA. The sintering temperature had a significant effect on the specific density, apparent density, total porosity, closed porosity, total volume of pores, and water absorption. It was proved that a broad range of the SS content is admissible in the raw material mass for the production of LECA. -

Utilization of Plastic Waste Polyethylene Terephthalate (Pet) As a Coarse Aggregate Alternative in Paving Block
MATEC Web of Conferences 280, 04007 (2019) https://doi.org/10.1051/matecconf /201928004007 ICSBE 2018 Utilization of Plastic Waste Polyethylene Terephthalate (Pet) as a Coarse Aggregate Alternative in Paving Block Wiku A. Krasna1,*, Rijali Noor1, and Denny D. Ramadani2 1 Lecturer of Faculty of Engineering, Lambung Mangkurat University, Indonesia 2 Student of Faculty of Engineering, Lambung Mangkurat University, Indonesia Abstract. PET plastic waste is found everywhere in Banjarbaru City compared to other plastic wastes. It is an excellent prospect to reuse the PET plastic waste. The demand of mountain rock and stone from natural resources increases as happened in Aranio Sub District, Banjar Regency. This research is expected to find one way of suppressing the growth of the number of stone mines or natural stone. Based on SNI 03-0691-1996, the classification of the paving block differentiated according to its usage class, one of which is the C quality used by pedestrians. PET waste used as a coarse aggregate previously processed into aggregate with the ratio of cement material, fine aggregate, a coarse aggregate of 1:6:4. PET waste is processed by melting PET and forming into aggregates. The paving with PET waste process by a hydraulic press machine and tested for strength after 28 days. The result of weight measurement with the specimen increases the amount of PET in the paving block mixture, the paving weight decreases as well as the compressive strength. 1 Preliminary 1.1 Background Natural resources are one of the essential assets for country’s/national development. Therefore, should be utilized as widely as possible for the interests of the people with attention to sustainability [1]. -

COARSE AGGREGATE for COMPOSITE PORTLAND CEMENT CONCRETE PAVEMENT (Tollway)
COARSE AGGREGATE FOR COMPOSITE PORTLAND CEMENT CONCRETE PAVEMENT (Tollway) Effective: January 30, 2012 Revised: October 29, 2012November 26, 2012 Coarse aggregate for Portland Cement Concrete shall be in accordance with Section 1004 of the Standard Specifications except as modified below for the lower layer of composite Portland cement concrete pavement. Add the following to Article 1004.02 of the Standard Specifications: “(g) Recycled Coarse Aggregate (RCA). If recycled coarse aggregate is specified for use in a concrete mix design, the recycled coarse aggregate will be generated from a Tollway approved source of existing concrete or asphalt pavement. The recycled coarse aggregate may be processed from a non-AGCS certified location. The processing of recycled coarse aggregates for reuse in hydraulic cement concrete shall be as follows: (1) Concrete pavement or structural concrete for recycled coarse aggregate from an approved source shall be broken with a guillotine (or similar) crusher, removed, and transported to a crushing location at a central recycling plant and be processed in accordance with IDOT’s policy memo for Recycling Portland Cement concrete into Aggregate except as follows. a. Removed concrete shall be crushed with an impact type crusher operating at less than full capacity to minimize the production of fines. Up to 5 percent of the recycled coarse aggregate from Portland cement concrete pavement sources may consist of asphalt containing particles. b. Washing of the crushed concrete coarse aggregate is required. The extra absorptivity of the recycled concrete aggregates shall be accommodated by keeping the stockpiled aggregates wet and at the batching plant by controlling the appropriate amount of water to the concrete mix to achieve the desired water to cement ratio.
