Introducing superabsorbent polymer (SAP) into white fair-faced concrete can achieve the purpose of internal curing, which is beneficial to popularization and application concrete. The effects SAP mixture curing water content on properties were investigated macroscopically through indexes, including slump, electric flux, standard cube compressive strength, tensile splitting strength. mechanism t...

Tahapan pelaksanaan konstruksi beton untuk menyelesaikan suatu proyek, salah satunya adalan pengecoran dan menjadi bahan utamanya. Dalam memenuhi mutu yang direncanakan, pengendalian penting dilakukan guna mendapatkan produk dihasilkan sesuai dengan spesifikasi telah direncanakan. Tujuan penelitian ini menganalisis pada struktur pondasi rakit. Metode analisis digunakan yaitu SQC peta kendali X ...

High Strength Self Compacting Concrete is a concrete innovation with the advantage of having high workability and quality. In this research, fly ash was used as filler. Tests carried out by using percentage 1%, conducting slump flow test curing time 14 days. The same also tested three types tests, namely test, l box v funnel 28 specimens are cylindrical dimensions 100 mm 200 mm. research result...

A sedimentological and palynological investigation was carried out on outcropping sedimentary rocks at Dogiyai, Papua, proposed to be named as the Mapia Formation. The age range is from Middle Miocene Pleistocene. lower Formation deposited Metroxylon type Nothofagus emarcida Zone, Early Pliocene. It comprised of three facies associations: tidal channel, point bar, flat deposits. tidally dominat...

This paper investigates the effects of properties fresh concrete incorporating shredded Polyethylene Terephthalate (PET) bottles and Manufactured Sand (M-sand) together as fine aggregates replacement in mixtures. The investigation to determine correlation were mainly experimental based experiments involved Slump Test, VeBe Test Compaction Factor Test. There two different batches prepared, which...

This paper investigates the mechanical and micro-interfacial properties of recycled concrete. Concrete specimens with brick coarse aggregate (RBCA) admixtures 0%, 25%, 50%, 75%, 100% were prepared. Apparent density, slump, tests carried out to evaluate behavior The evolution laws parameters such as compressive strength, peak strain, elastic modulus concrete tested analyzed. Combined numerical a...
