Mechanisms of Concrete Confinement

Mechanisms of Concrete Confinement Concrete under uniaxial compression tends to expand laterally and the longitudinal strains generated by such loading give rise to transverse tensile strains. which cause vertical cracking and failure in concrete. Lateral

Cracking In Concrete Walls: Causes, Types and Mitigation

TeamCivil Repair

Cracking In Concrete Walls Cracks in concrete walls and slabs are a common occurrence. They appear in floors, driveways, walks, structural beams, and walls. Cracking can not be prevented but it can be significantly reduced

Chloride Ingress into Concrete

TeamCivil Concrete, Durability

For concrete structures in chloride-containing environments, the ingress of chlorides can take place in different ways. Through uncracked concrete, the ingress mainly takes place by capillary absorption and diffusion. When a relatively dry concrete is

Gap-graded Aggregate

TeamCivil Concrete, Materials

ِِِِِAggregate particles of a given size pack so as to form voids that can be penetrated only if the next smaller size of particles is sufficiently small, that is, there is no particle interference. This

Concrete Additives

TeamCivil Concrete, Materials

Concrete Additives Concrete additives are fine materials which are generally added to concrete in significant proportions (around 5–20 %). They are used to improve or obtain specific fresh and/or hardened concrete properties. European Standards lists

Loads on Falsework and Formwork Falsework and formwork shall be designed to carry all the loads that they will be subjected to till the time when the permanent structure they support gains sufficient strength to

Non-Industrial Floors: Types, Loading, Joint and crack requirements

TeamCivil Analysis, Concrete Design, Structural, Structures

Non-Industrial Floors This category includes all floors except warehouse and factory floors. Though non-industrial floors get little attention, they are actually far more numerous than their industrial counterparts. Non-industrial floors are usually easier to design and

Lumber Formwork

TeamCivil Construction

Lumber Formwork The general term lumber refers to both “Dimension lumber” and “Timber”. Dimension lumber means a piece of lumber 38 to 102 mm inclusive in smaller dimension. Timber means a piece of lumber 114 mm or
