Sulfur concrete construction industry pdf

As you can see, these examples reacted very well against acid and virtually show no corrosion in the 4-weeks of immersion in 6. Above examples suffer from corrosion in base environment and only sulfur concrete with Dicyclopentadiene resisted against corrosion after 4 weeks of immersion in base soluble and only lost 7. Compressive strength of samples has inverse relationship with water cement ratio and compressive strength decreased with increasing amounts of sulfur and samples' resistance becomes less than normal sulfur samples.

Flexural Strength Test. Testing the Samples' Resistance Against Molten and Frigidity Weight loss of typical samples of sulfur concrete was almost two times more than sulfur coated samples due to pores in conventional sulfur concrete and water penetration.

Testing Resistance Against Sulfuric Acid. Weight changes in conventional sulfur concrete samples are more than sulfur coating cement concrete samples.

Glass fiber in sulfur concrete has significant impact on the risistance of sulfur concrete and it has more resistance than conventional sulfur concrete samples. Replacement of some modified sulfur with fly ash increases the compressive strength and tensile strength and fill the pores of the concrete caused by fly ash and increases the concrete density and hardness and reduces the modulus of elasticity and coefficient of thermal expansion of sulfur concrete.

The use of recycled aggregates in concrete reduces sulfur concrete compressive and tensile strength and decreases the hardness and modulus of elasticity of concrete and increases the coefficient of thermal expansion. Have higher compression resistance compared to conventional sulfur concrete samples with natural aggregates and without fly ash.

Table1: The average results of tests carried out on samples of sulfur concrete and cement concrete. In experiments on sulfur concrete samples, the effect of additive on increasing compressive strength of sulfur concrete and preventing it from the loss was apparent, and preference of Dicyclopentadiene over SMZ was clear.

Behfarnia el al. Toggle navigation. Copy the following to cite this article: Khademi A. Article Publishing History Received: Accepted: Sulfur concrete consists of a mixture of aggregates, sulfur, filler and additives for preserving elastic property of concrete and preventing loss of resistance, an additional matter is used like SMZ, SRX, DCPD Experiments carried out on sulfur concrete examples: 1. The covering cement concrete with modified sulfur Lee el al.

Flexural Strength Test Fig. Sulfur concrete with fiber Margal el al. Sulfur concrete with electrolytic manganese residual as a filler Yang el al. Concrete sulfur in water Yahia el al.

Melting and freezing resistance of these concretes are almost double the normal sulfur concrete samples and weight changes of these samples in acidic environments is always less than typical sulfur concrete samples. Lee el al. Margal el al. Shin el al. Yahia el al.
