Utilisation of used White Paper for Papercrete (Mechanical and Economic Characteristics)
Abstract
Papercrete is a construction material created by combining wastepaper with cement and additional
substances. It serves as a replacement for traditional concrete and provides advantages like as
waste reduction and the mitigation of construction's environmental impact. It serves as a
sustainable and eco-friendly substitute for conventional concrete. The objective of this study is to
quantify the compressive and flexural strength of papercrete, assess the manufacturing cost of
papercrete, and identify the optimal paper proportion in the concrete mix based on both
mechanical and economic factors.
An experimental study was conducted to examine the mechanical and economic properties of
papercrete with different paper proportions. White wastepaper has been incorporated into the
concrete mixture. The ratio of cement to sand remained steady at 1:6. This mix design incorporates
six different ratios of wastepaper to cement, ranging from 0% to 20% in increments of 4%. The
sample manufacture took place at Pusat Inovasi Material Vulkanis Merapi UII, while the
laboratory testing was conducted at Laboratorium Bahan Konstruksi Teknik UII. A survey was
done to obtain production cost data from multiple vendors located near Kaliurang Street.
The compressive and flexural strengths of papercrete are generally reduced when white
wastepaper is used in papercrete ingredient. The strength decreases with increasing wastepaper
content. The cost of wastepaper papercrete is higher than that of normal concrete (0% wastepaper).
The cost of papercrete made using white wastepaper increases with its composition. The results
shows that there is not a optimum blend of papercrete made with white waste paper in terms of
strength and production costs.
