Design Example: Sustainability in Concrete Building01:26

Design Example: Sustainability in Concrete Building

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground cistern.
Portland Cement01:21

Portland Cement

Portland cement is the essential binding ingredient in concrete, made from finely ground materials including lime, iron, silica, and alumina. Lime is derived primarily from limestone, marble, marl, seashells, and clays, which also supply iron and alumina, while silica is sourced from sand, chalk, and bauxite. Contemporary manufacturing of Portland cement is a significant source of carbon dioxide emissions, prompting research into reducing its content in concrete through alternative...
Passive Diffusion: Overview and Kinetics01:17

Passive Diffusion: Overview and Kinetics

Passive diffusion is a critical process that allows small lipophilic drugs to cross the cell membrane along a concentration gradient. This mechanism's efficiency depends on four primary factors: the membrane's surface area, the drug's lipid-water partition coefficient, the concentration gradient, and the membrane's thickness.
When administered orally, drugs establish a substantial concentration gradient between the gastrointestinal (GI) lumen and the bloodstream, expediting their diffusion into...
Effects of Chemicals: Overview01:27

Effects of Chemicals: Overview

Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...
Pozzolans01:21

Pozzolans

Pozzolans are siliceous or aluminous materials blended with Portland cement. They interact with the calcium hydroxide produced during the hydration of Portland cement and contribute to improved strength and durability of concrete. The pozzolanic activity, a measure of a pozzolan's effectiveness, is typically assessed using the strength activity index, as defined in ASTM C 618-93, which calculates the ratio of the compressive strength of cement mixtures with and without pozzolan.
Fly ash is a...
Effects of Air-entrainment in Concrete01:28

Effects of Air-entrainment in Concrete

Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

Summary

Cement and lime building materials were tested for emissions. Neopentyl glycol (NPG) was a dominant Volatile Organic Compound (VOC) from cement products, reaching high levels and showing fast chemical diffusion through materials.

Area of Science:

  • Building Science
  • Environmental Chemistry
  • Material Science

Background:

  • Building materials can emit Volatile Organic Compounds (VOCs), impacting indoor air quality.
  • Understanding the specific VOCs emitted and their transport mechanisms is crucial for material selection and health risk assessment.

Purpose of the Study:

  • To quantify and identify Volatile Organic Compounds (VOCs) emitted from cement- and lime-based building materials.
  • To assess the permeability and chemical diffusion characteristics of these building materials.

Main Methods:

  • Emissions of VOCs were measured using an environmental chamber for cement and lime-based materials.
  • Material permeability was evaluated using a dual environmental chamber setup to study chemical diffusion.

Main Results:

  • Neopentyl glycol (NPG), a non-routinely analyzed VOC, was found to be the dominant emission from cement-based products, reaching up to 1400 μg m(-3) (93% of total VOCs) within 72 hours.
  • NPG concentrations remained relatively stable between 24 and 72 hours.
  • Building materials demonstrated significant permeability, facilitating rapid chemical diffusion and reaching equilibrium within 6 hours.

Conclusions:

  • Cement-based building materials can be significant sources of specific, less-monitored VOCs like NPG.
  • The high permeability of building materials suggests they can readily absorb and release chemicals, influencing indoor environments.
  • Further investigation into NPG and other non-targeted VOCs from building materials is warranted for accurate indoor air quality assessments.
