Slabs precast on site, for street channeling closure. Karnataka, India.

Architectonic Concrete, S.L. performed tecnical assessment to all the teams involved in these works, untill these first precast slabs were placed:
to the architects while in design fase, moulds-making process, precast workers and engineers on the site... all local, in northern Karnataka state for a cement manufacturing group, who was the whole task promoter.

First image shows weighting for a precise dossage of pigments and fluidifier.

Mastering self-compacting concrete allows for good precast in the very same erection site, thus eliminating factory and cost of carriage for the terminated elements.

Architect wished a terracotta color for the slabs, which we decided to integrate on the fresh mix, to obtain total color durability under the strong solar exposure in the long run.

Then color was set by mixing white cement dry with 3% w.c. iron oxides, which are fully compatible with the fluidifiers.

Though our concrete mixer was elementary, it sufficed perfectly, since most important is the dossage precision of the fresh mix, speciallly the fillers, and over all: the water ammount.

Slabs demould after 24 hours, only. That concrete is able for 4 Mpa. bending resistance, at that time.

Besides, elevation fixings are embeded in the material, and conected to its inner iron bar reinforcement.

Slabs surface is that of the moulds negative, with slotted diagonals to avoid slipery, when wet.

Right after demould slabs turn up side and place directly in their intended location, for street sidewalk while as a registrable closure of the services gallery to the whole residential urbanization.

This project was inspired by our experience with a similar project of Barcelona (Spain), some 20 years ago, though with a different aesthetics, more granite-like, but similar conception and processes.

Textured building's façade. Las Palmas de Gran Canaria. Spain.

This residential building is cladded with mass-colored architectural concrete pannels, by proper dosage of three different "black" tones, to resemble basalt-like.

The texture for the exposed surface was obtained by flexible skins, which can be cutted as for the intended pannel sizes, so avoiding fake joints.

Precast façade claddings allways require a detailed project for the elements explode, identifying type and series of elements and intended location for each. Precasters can help architects while in that desing phase, too.

Architectonic Concrete S.L. assisted the project phase of the architect for this building, and to the precaster for moulds, prototypes and serial manufacturing of this architectural concrete.

Touristic residentials, bungalows. Cayo Largo, Cuba.

Architectonic Concrete S.L, supplied engineering assistance for three years to the cuban corp. Caribbean Sodeal,S.A, on complete precast solutions.

Sometimes these solutions involved difficult logistics, as in this case: a final erection of the precast pieces in the Cayo Largo del Sur Island, including foundation elements, by ship from the main island.

This image shows the structural pannels system.

Teracotta-like and wooden color comes from different dosages of yellow, red and black pigments, grey cement based mix.

The texture for the exposed surface of the pannels is that of wooden tabs with natural grain patterns. That texturing was achieved by moulds with flexible framed skins.

The dimmensions of precast beams and pannels reached full heights and lengths between storeys and columns that, together with the logistics and handling constrains, made a maximum around 2 ton. weight for the elements.

The key issue for the quality achieved in this industriallized construction project was the previous many hours commited in the technical office task: on the most practical conception, then calculus, full projected details for every element and union, well in advance of the manufacturing phase.

Thus, such a meticulous project made posible the buildings erection with strict dimmensional tolerances, in the range of milimeters.

The whole compound erected for this touristic resort was of 24 "bungalows" like this, together with much bigger common service buildings, on record time and great quality, to all extends, as it was evidenced by the pass of a hurricane, cat. 3, right through the site, few after these pics were taken, registering not relevant dammage on the works.

Architectonic Concrete S.L. provided his knowledge for this project to the technical office task, moulds, fixings, and colors and textures execution.
