Pervious concrete has been reported as a viable solution to reduce stormwater run-off, the heat-island effect, road noise, and pavement flooding. Previous researchers have focused on analysing structural properties functionality of pervious concrete. However, relatively few studies conducted into addition supplementary cementitious materials (SCMs), such calcined clay, in its effect long-term d...

In this study, a combination of geopolymers including Rafsanjan Natural Pozzolan (RNP), Cement Kiln Dust (CKD), and an activator such as Calcium Carbide Residue (CCR) or NaOH was used to stabilize improve the poorly graded sandy soil. Factors type, concentration, CKD RNP content were studied. Chemical compounds soil abovementioned materials investigated using X-ray Diffraction (XRD) Fluorescenc...

Geopolymer concrete has been developed as a replacement for conventional with other pozzolan materials, which have high silicate alumina content. Fly ash is material that contains of 22%. The content Al and Si increases the compressive strength concrete. High-calcium fly abundantly found in Indonesia. However, it not widely used industry or research, this due to fast hardening time Therefore, p...

The ever-increasing cost of cement and its production harmful carbone dioxide (CO2) has led development actors to continuously search for less environmentally polluting low-cost binders. Hence the interest in valorisation agricultural resources through different binders such as silicate elaboration geopolymers at low manufacturing temperatures (<100 °C). In this study, Ingessil industrial ri...

Perbaikan tanah dengan metode stabilisasi pada lempung ekspansif merupakan suatu hal penting yang harus dilakukan sebelum mendirikan bangunan. Tanah adalah dapat mengalami kembang susut ketika perubahan cuaca. Salah satu mencampur bahan tambah mampu merubah sifat-sifat secara kimiawi. Abu sekam padi mengandung silika dan material pozzolan hasil dari pembakaran kulit umumnya hanya dibuang tidak ...

This paper focuses on producing a natural hydraulic lime (NHL) mortar with metakaolin, expanded perlite and tuff additives for the purpose of repairing historic masonry. The experimental study was based laboratory tests determining mechanical physical properties NHL mortars mineral additives, under standard water curing conditions at 7, 28 90-day testing periods. Following preliminary selecting...

Peat is a problematic soil, and it common problem faced by engineers in construction. The characteristics that have been noted before are high moisture content, poor shear strength, great compressibility, long-term settlement. For this research study, focuses on stabilizing peat soil using EPP CaO. There three main tests were conducted study: index properties testing, compaction Index Propertie...
