REPUBLIC PORTLAND CEMENT TYPE 1P Buildmore Construction Depot
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone.
PORTLAND CEMENT ASTM C150 TYPE I
Portland cement is a complex product obtained from unprocessed common natural materials: limestone and clay. Consequently, the characteristics of Portland cement clinker may vary from one cement plant to another.

Introduction Safe disposal of liquid radioactive waste (LRW) is a pressing problem that should be solved to ensure successful progress of nuclear power engineering. Cement materials, primarily Portland cement, are widely used in nuclear power engineering and for disposal of solid and liquid radioactive waste (RW).

Portland cement is recommended by the authors [22] in protection from gamma radiation. The aim of the present work is firstly to prevent the free movement of contaminants in solid glass waste by immobilization of this glass waste in cement as a simple and low-cost technique of containment of the wastes inside a stable solid form in order to be.

Portland cement, the most widely used construction material in the world, is a synthetic material made by burning a mixture of ground limestone and clay, or materials of similar composition, in a rotary kiln at a sintering temperature of 1450 °C.
The Definitive Guide to Understanding Portland Cement & Its Uses
γ-C 2 S has high potential for use as a construction material with the additional benefit of CO 2 absorption due to its high carbonation reactivity. This study quantitatively investigates the evolution and influencing factors of the microstructure of the γ-C 2 S compact molded by cold isostatic pressing, including microhardness, porosity, pore structure, and carbonation degree at different.

Properties of Ordinary Portland Cement
In this study, samples of commercial Portland cement mixed with 30% weight of crushed waste silicate glass were prepared in the shape of well-dried cylinders. Then, their physical and mechanical properties were investigated for two types of samples: samples without exposure and samples with exposure to gamma-ray and neutron irradiation.

Cubic Portland cement specimens were casted and exposed to the gamma radiation of a 60Co multipurpose irradiator, at IPEN-CNEN/SP. The effects of doses between 1000 kGy and 4000 kGy are evaluated by X-Ray Diffraction, Scanning Electron Microscopy, X-ray micro tomography, neutrongraphy and neutron scattering.

In this study, γ -dicalcium silicate ( γ -C 2 S) was incorporated into ordinary Portland cement (OPC) to sequester CO 2 to enhance the carbonation resistance of cement-based composite materials. γ -C 2 S can react with CO 2 rapidly to form vaterite and high dense SiO 2 gel which could block the pores off and then inhibit further diffusion of CO2 into the system.
