Sweating Slab Syndrome and Efflorescence Efflorescence is a crystalline deposit of water-soluble salts left on the surface of masonry and concrete as the water evaporates. Efflorescence is a partner of Sweating Slab Syndrome. This article is intended to address only efflorescence in concrete floors and more specifically, secondary efflorescence.

Working With Concrete Concrete is in fact the most used material for construction in the world and has been in use since the age of the Roman Empire. Concrete is a mixture of aggregate (sand and gravel) combined with water and cement.Depending on the ratio of these parts the concrete can be stronger or weaker. Concrete hardens in a process known as hydration which is caused by the reaction between water and cement. Adding too much water can weaken the concrete.For most deck projects it is practical to buy bags of premixed concrete that are prepared by adding water and mixing. You can use a wheelbarrow and mix with a hoe to a consistency that is able to move and fill voids but is not too wet and soupy.oncrete is in fact the most used material for construction in the world and has been in use since the age of the Roman Empire.

Pervious Concrete The runoff coefficient or curve number of the paved area should be that of the subgrade soils in the compacted state. Over-compaction of the subgrade during construction will prevent necessary infiltration. Structurally, pervious concrete is weaker than plain concrete with compressive strengths less than 1000 psi. Due to the lower strengths, pervious concrete pavements are acceptable for light duty applications such as car parking facilities, pedestrian areas, and low traffic pavements.

- Mixing bags of concrete isn't complicated. You add some water, stir it up and pour it out. But to get the most strength from the concrete, you have to recognize when it has just the right amount of water mixed in. Too little water and the particles in the mix won't stick together.

What is Concrete? What is Concrete: Concrete & Cement Defined. Contrary to popular belief, concrete and cement are not the same thing; cement is actually just a component of concrete. Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement.Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates.ortland Cement-The cement and water form a paste that coats the aggregate and sand in the mix. The paste hardens and binds the aggregates and sand together. Water-Water is needed to chemically react with the cement (hydration) and too provide workability with the concrete.

Gunite â Concrete Construction Fiberglass pools win the battle in ease of maintenance as well. Concrete pools require maximum use of the pool’s filter because of metals and alkaloids that leech into the water through the plaster finish. Fiberglass pools also do not require as many chemicals over time because the surface of fiberglass is nonporous.

- For concretes of equal cement content, air content, and slump, the 28-day strength of a water-reduced. concrete containing a water reducer can be 10% to 25%. greater than concrete without the admixture. Despite re-. duction in water content, water-reducing admixtures may. cause increases in drying shrinkage.

Sweating Slab Syndrome and Efflorescence Sweating Slab Syndrome and Efflorescence A slick and slippery concrete floor is not normal! A wet floor may cause accidental slips, trips, and falls and can be very dangerous for forklift and other machinery as they may be unable to brake or stop when needed. Most often, the cause of a damp concrete floor can be explained as Sweating Slab Syndrome. Most times Sweating Slab Syndrome is accompanied by concrete efflorescence. Efflorescence appears as a white, powdery substance often in a map cracking pattern and is the result of the evaporation of the accumulated moisture.

An excess amount of entrapped air held within the concrete by a high percentage of material passing the 600 µm, 300 µm, and 150 µm (No. 30, 50, and 100) sieves, resulting in a sticky or tacky concrete that can become more easily sealed when floating or finishing it at any early age.

What chemicals breaks down concrete? Report Abuse. Chemical agents that can destroy concrete may be found in the ground. Sulfates and acids naturally occurring in soil and groundwater are the agents most likely to attack concrete. The effects can be serious leading to expansion and softening of concrete.

How Concrete Goes Bad How Concrete Goes Bad. It’s Porous. Somewhat surprisingly, concrete is porous. While it is very hard, it also has millions of. tiny pores and microscopic cracks. Looking at concrete under magnification reveals the. pore and capillary structure, and it is remarkable how many tiny voids there are.

Concrete Concrete is a composite material composed of aggregate bonded together with a fluid cement which hardens over time. Most use of the term concrete refers to Portland cement concrete or to concretes made with other hydraulic cements, such as ciment fondu. However, road surfaces are also a type of concrete, asphaltic concrete, where the cement material is bitumen.

Sustainable Concrete The leading material in Sustainable Construction Cement is one of the many constituents of concrete, part of the glue that holds the other materials together. Concrete is made by mixing cement, supplementary cementitious materials, water, fine aggregate (sand), coarse aggregate (gravel or crushed stone) with or without admixtures, reinforcement, fibres or pigments.oncrete is easily and readily prepared and fabricated in all sorts of conceivable shapes and structural systems. Its great simplicity lies in the fact that its constituents are ubiquitous and are readily available almost anywhere in the world 1.

The paste is generally mixed in a high-speed, shear-type mixer at a w/cm (water to cement ratio) of 0.30 to 0.45 by mass.
