TLDR
In this article, the authors investigated the relationship between porosity and compressive strength and presented mathematical models that have been developed to describe this relationship and concluded that the equation derived by Hoff could effectively be used to predict the compressive strengths of foamed concrete mixtures containing high percentages of ash.About:

Changes in portlandite morphology with solvent composition: Atomistic simulations and experiment
TL;DR: In this article, a new analysis tool was developed to quantify the experimentally observed changes in morphology of portlandite, allowing the calculation of the relative surface energies of the crystal facets.
Journal ArticleDOI
A classification of studies on properties of foam concrete
TL;DR: In this article, the authors classify literature on foam concrete in terms of constituent materials (foaming agent, cement and other fillers used), mix proportioning, production methods, fresh and hardened properties of foam concrete.

Geopolymer foam concrete: An emerging material for sustainable construction
TL;DR: In this article, the authors address some of the sustainability questions currently facing the cement and concrete industry, in the context of the utilisation of foam concretes based either on ordinary Portland cement (OPC) or on geopolymer binders.
Journal ArticleDOI
Properties and applications of foamed concrete; a review
TL;DR: Foamed concrete possesses characteristics such as high strength-to-weight ratio and low density as discussed by the authors, which reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the labor cost during construction.

The relationship between porosity and strength for porous concrete
C. Lian,Yan Zhuge,Simon Beecham +2 more
TL;DR: In this article, the authors developed a mathematical model to characterize the relationship between compressive strength and porosity for porous concrete by analyzing empirical results and theoretical derivations, which was derived from Griffith's theory.

Investigations on the relationship between porosity, structure and strength of hydrated Portland cement pastes. II. Effect of pore structure and of degree of hydration
TL;DR: In this article, the main factor influencing the strength properties of the obtained samples was found to be their porosity, however pores with radii of less than 10 nm affected the resultant strength only negligibly.

The effect of high fly ash content on the compressive strength of foamed concrete
TL;DR: In this article, the compressive strength of concretes cured under sealed conditions was investigated and it was shown that up to 67% of the concrete could be replaced without any significant reductions in strength.
Journal ArticleDOI
Porosity and permeability of foamed concrete
TL;DR: In this article, the authors investigated the effects of replacing large volumes of cement with both classified and unclassified fly ash on the properties of foamed concrete and found that water vapour permeability increased with increasing porosity and ash content.

Investigations on the relationship between porosity, structure and strength of hydrated portland cement pastes I. Effect of porosity
M. Röβler,I. Odler +1 more
TL;DR: In a series of cement paste specimens made with different water-cement ratios and hydrated for different times, the relationship between porosity and strength was determined in this article for a range of porosities between 5 and 28 per cent.
