The Difference between Concrete and Screed
Concrete and screed and are essentially formed of the same basic ingredients – cement, aggregates and water. But what makes them different is- the size of aggregates, the cement grade, mix consistency, and of course their intended application or use. Composition and Mix Proportion Concrete in its simplest form is a rock like mass formed […]
The Pros and Cons of Manufactured Sand
Before we get into the advantages and disadvantages of manufactured sand, what exactly is manufactured sand? Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sand-sized particles. Natural sand, on the other hand is the naturally formed sand extracted from river beds. The Manufacturing Process Rocks or quarry stones […]
The Different Aggregate Options
Aggregates are inert, granular materials which form a major component of screed and concrete mixes. With urban expansion and environmental constraints putting a strain on the naturally occurring aggregate sources such as sand, gravel and crushed rock, the construction industry is now widely exploring other sustainable and economically viable resources, to meet their ever-growing demand […]
The components that make a good screed: A quick guide
Every detail right from the type of cement and grade of aggregate to the method of storage of materials, play a major role in determining the quality of a screed. Here are a few tips on getting the details right for cement-sand levelling screeds. Read more:
Checklist for onsite supervision for screeding Tips 4 – 6
Following on from Checklist for onsite supervision for screeding Tips 1 – 3 we present tips 4 -6. 4. Screed Mix Check that the raw materials and the mixing of screed are correct. The ideal mix proportion for normal cement/sand screeds is – 1:3 to 1:5 – that is 1 part Portland Cement ( which […]
Surface Regularity of screeds for normal accuracy flooring
Surface regularity is generally defined as the limitation of deviation of the surface beneath a straightedge laid flat on the surface. As the measurement criteria varies for different types of screeds and flooring, it is important to ensure that the measurement is in compliance with the particular specification. Furnished here are the details of surface regularity measurement […]
Checklist for onsite supervision for screeding Tips 1 – 3
From the verification of the screed specification to the installation of the screed and the adoption of screed protection measures, a successful screeding project requires meticulous attention and supervision at every step. Given here is a screeding checklist that will be useful in verifying all the important aspects of screeding at the work site. 1. […]
How to install rigid floor insulation on ground floor concrete substrates before screeding
The following information is a guide to the installation of rigid insulation on ground floors to receive a screed. The correct installation of polythene DPM, rigid insulation and separating layers are highly important not just for the overall integrity of the screed system but for the quality of the entire flooring. We have made an […]
The importance of flatness of concrete substrates for the installation of unbonded screeds
A flat concrete substrate is one of the most important pre-requisites for the application of unbonded screeds or floating screeds. The purpose of keeping a screed unbounded is to allow the screed to slip on a polythene membrane, providing a suitable screed construction for depths of over 50mm. Taking into consideration the fact that the screed will […]
Procedure for the mixing of screed using a screed pump
The quality of a screed is highly reliant on the method of mixing of the screed. Force action mixing of screeds using screed pumps is proven to yield screed mixes that are clearly superior in quality and homogeneity as compared to the usual screed mixes produced using free fall mixers. Given below are the steps […]
