Abstract

Perkembangan teknologi beton saat ini membuat konstruksi beton semakin banyak digunakan sebagai bahan konstruksi. Beton umumnya tersusun atas semen, agregat dan air ,jika diperlukan biasanya dipakai bahan tambah(admixture). Penelitian ini bertujuan untuk membandingkan kuat tekan beton normal tanpa tambahan Sika Tilefix-200 TA dengan kuat tekan beton yang campurannya telah ditambahkan Sika Tilefix-200 TA sebanyak 5%, 10% dan 15% dari berat semen PCC. Hasil pengujian kuat tekan pada umur 28 hari menunjukan hasil sebagai berikut : kuat tekan beton variasi 1(tanpa tambahan Sika Tilefix-200 TA) sebesar 39,709 MPa , kuat tekan beton variasi 2 (dengan tambahan 5% Sika Tilefix-200 TA dari berat semen PCC) sebesar 31,777 MPa, kuat tekan beton variasi 3 (dengan tambahan 10% Sika Tilefix-200 TA dari berat semen PCC) sebesar 30,981 MPa, dan kuat tekan beton variasi 4(dengan tambahan 15% Sika Tilefix-200 TA dari berat semen PCC)sebesar 34,042 MPa. Penambahan Sika Tilefix-200 TA sebesar 5%, 10%, dan 15% dalam campuran beton belum bisa meningkatkan kuat tekan beton melebihi kuat tekan beton normal(tanpa tambahan Sika Tilefix-200 TA)

Abstract

Low humidity during weaving processes causes cotton yarns to become brittle and prone to breakage. To address this issue, polyacrylate has been explored as an alternative sizing agent due to its flexibility and high adhesion. This study aims to review the effectiveness of polyacrylate sizing on cotton yarns in dry environments. A narrative literature review was conducted by analyzing ten scientific articles published between 2021 and 2025 from reputable databases. The findings show that polyacrylate can enhance yarn tensile strength by up to 30%, reduce energy consumption, and extend the lifespan of weaving machinery. Moreover, bioactive-based polyacrylate formulations support sustainability through improved biodegradability and environmental friendliness. However, certain formulations still pose compatibility challenges with textile finishing processes, such as reactive dyeing and digital printing. Further reformulation and industrial-scale testing are necessary to ensure both technical performance and ecological safety. This review offers strategic insights into the development of future sizing agents that are adaptive, efficient, and sustainable
